Yeah it defently gets worse! when they get bigger they will dump absoultly everything that may have food in it, plus the poop gets bigger! I have to clean out my coop at least 2 times a week!
I moved my CX's to the coop at two weeks, with just a heat lamp from the brooder, and they survived a mid may snowstorm, with no losses. I started free ranging them at 3 weeks on my acre, and took away the brooder lamp. I feed them at right before sunset, when I feed my other chickens. There is very little feed left mid morning when I let them out to range. They have also been on naturaly grown, home mixed feed, which averages about 20% protien. The feeder is also set up so they can not lay/sleep in it. They are growing slower, we just slaughtered half of them earilier this week. At 10 weeks they are dressing out about 4 to 4 1/2 lbs. The carcasses also had very little fat on them. The rest will wait a couple more weeks.
These bird seem to act more like normal chickens, than other CX's. They do like to roost on lower roosts, they forage, are active, follow my older hens everywhere, and still come running (wobbling all the way) when they see a feed bucket, or see someone heading into garage (where feed is kept). I have not lost any since moving them outside.
Dose anyone know if there are different strands of Cornish X's, some that grow slower than others?
