Chicken experiment #1, day 28
Pictured above are two of the chickens in the experiment, a rhode island red rooster and a cornish cross. The cornish cross weighs 25 ounces, the rhode island red weighs 8 ounces.
At this point most of the chickens have a good start on their feathers and I'm reducing the amount of heat that they get to gradually acclimate them to room temperatures.
I am restricting feed on the cornish cross to slow their growth and prevent ascites and while this may slow their theoretical growth, reducing feed reduces mortality for the chickens.
The cornish up to now have been about double the amount of labor of the other chickens -- they require quite a bit of bedding to keep their bin clean.
I've reduced the amount of feed being offered to the other chickens to reduce waste. When the feeders are full they flick it out of the feeders onto the floor of the bin. With the feeders 2/3rds full they waste less of the feed.
