Summing up s chicken experiments

Black Australorp pulletThose of you who have been
following my chicken experiments here all year will probably find most
of this old news, but I summed up the year’s data over on my
homesteading blog.  Drop by for information on:

Finally, you might be
interested in this
Appalachian
forest pasture study
,
even though it uses sheep instead of chickens.  That should be
enough reading to last you all weekend!

Establishing new pasture perennials

Bluegrass seedlingsBetween ragweed shading the
ground and me leaving one flock of broilers in the same pasture for
three months, the soil there was pretty much bare.  So I decided
to set the area aside for long term rejuvenation rather than trying to
turn chickens back into it anytime soon.




After removing the
ragweed (
before it went to seed), we planted
a combination of oats, alfalfa, Austrian winter peas, clover, and
Kentucky bluegrass.  I have to admit that the combination of
species is the result of me being over-excited and not thinking
everything through.  I probably would have been better off simply
planting bluegrass and clover for a solid spring pasture or a taller
grass (timothy or orchardgrass) and alfalfa for a good summer pasture,
leaving out the annuals altogether.  Live and learn!




Clover seedlingsDespite my enthusiastic
mixing, the seedlings seem to be doing relatively well so far. 
The bluegrass and clover seedlings are well represented beneath the
taller oats and peas, although I can’t quite tell if alfalfa is present
or not.  The tricky part will be whether the dying oat leaves
shade out the perennials too much over the winter, or whether they just
treat the grass and clover to a quick influx of nitrogen to fuel their
spring growth.




The other sticking point
could be the alfalfa.  With most pasture plants, if you don’t get
a good stand, you can just reseed in the spring and fill in any
gaps.  However, alfalfa  seedlings don’t like to sprout
anywhere near other alfalfa plants, so if just a few come up, we’re out
of luck.  On the other hand, I do have lots of other pastures to
play with, so if the alfalfa fails here, I’ll try again elsewhere.




Here are some statistics
in case you want to follow my lead:

Species Price per
pound (2011)
Planting time
(zone 6)
Annual or
Perennial
Seeding rate
(lbs/1000 sq. ft.)
Oats $0.33 8/1 – 9/15 Annual 3 (when planting alone as a
cover crop)

0.8 (when mixed with other plants as a nurse crop)

Austrian winter peas $1.08 8/15 – 9/15 Annual 2.3 (alone)

1.4 (nurse crop)

Alfalfa $2.75 8/15 – 9/1 Perennial 0.23
Kentucky bluegrass $3.75 9/15 – 11/1 Perennial 2 to 3
White clover $5 8/15 – 9/15 Perennial 0.05 to 0.2



As you can see, seeds
for perennial pasture plants are pricey.  But once you realize
that you don’t have to plant nearly as many of those tiny seeds, the
cost for reseeding a small homestead chicken pasture is pretty
reasonable.  Even if you don’t have a big bare patch of ground
like I did, you can overseed grass and clover into existing
pastures.  And if you’ve missed the boat for fall planting, don’t
worry — you have another window in the spring.



Our chicken waterer takes the experimentation
out of clean water.

How much food do chicks need

Six week old chick on pastureI’ve written before about how
much to feed adult chickens
.  But what about growing chicks whose needs change almost daily?

One option is to give them free access to an automatic chicken feeder, but then you’ll have to worry about attracting rats into the coop and will also end up with lazy chickens who don’t forage.  To keep my chicks hunting for bugs (thus paying the least for storebought feed), I give my chicks a certain amount of feed in the morning and then leave them on their own for the rest of the day.


Success With Baby Chicks has a handy table telling how much feed chicks need per day, which I’ve tweaked a bit and then reproduced here.  These figures assume you’re raising heritage breed birds — Cornish Cross chickens need more food faster — and that the chicks aren’t getting anything from pasture.  Robert Plamondon estimates that it takes about 7.7 pounds of chicken feed to raise a chick to the twelve week age at which I recommend slaughtering heritage broilers.  Here are the specifics:

Age Pounds of feed per chick per day Cups of feed per chick per day
0 – 7 days 0.014 0.056 (a bit less than a tablespoon)
8 – 14 days 0.029 0.116 (nearly two tablespoons)
15 – 21 days 0.043 0.172 (nearly three tablespoons)
22 – 28 days 0.057 0.23 (about a quarter of a cup)
5 – 8 weeks 0.093 0.372 (a bit more than a third of a cup)
9 – 12 weeks 0.146 0.584 (a bit more than a half of a cup)

 

So, for example, a six week old chick would need around 0.093 pounds of food per day, or a bit
more than a third of a cup.  If  you had 14 chicks of that age, you’d need to give them 1.3 pounds of food per day, or about 5 cups.  (A pound of chick feed is roughly equivalent to a quart or four cups.)


Despite being armed with all of this data, I have to admit that I’m pretty sure I fed our first three batches of chicks this year more than they needed.  First of all, they were living on pasture, so the chicks were getting a good amount of their nutrition from insects, worms, and clover.  Second, I actually ended up feeding them more than the recommended amount for birds who don’t have access to pasture.  It’s just so easy to think your chicks are starving when they come peeping to greet you at the gate, but the truth is that chicks expect treats when they see me, so they scamper over even if their crops are bulging.


The two sets of Black Australorps I raised are a good example of the fact that overfeeding doesn’t lead to any extra meat.  At 12 weeks, I’d fed our first batch of australorps 10.79 pounds apiece, and the cockerels dressed out to 1.87 pounds each.  The second batch “ate” 15 pounds of feed apiece, and the cockerels dressed out to 1.76 pounds apiece.  Clearly, the extra feed I gave to the second batch just went to waste.



Full cropBut my gut tells me that even feeding using the chart above will waste storebought food in when chicks are getting a lot of nutrition from pasture.  Which brings me to a better way of estimating whether you’re feeding pastured chicks enough.  With my final batch of
chicks for 2011, I’ve taken to peering at their crops a couple of times a day, and have noticed that even though I’m feeding my chicks only about 80% of their recommended allotment, the chicks’ crops are always full.  Now, it’s possible that malnourished chicks could still have full crops due to eating things that aren’t really food since they’re feeling hungry, but our chicks are also perky, with shiny feathers and seemingly stout bodies.  I figure that as long as
chicks look healthy and have full crops, they’re getting enough (or too much) food, but I won’t know for sure until I kill the broilers at 12 weeks and weigh their carcasses.
