The rescue meaties have been with me for 22 days. I'm estimating their age to be around 6 weeks old now. They are all doing great. Only a few of them (3 cockerels) are getting larger than normal. A fourth one was but I convinced him "Baby" to spend more time moving around and less time sitting in front of the feeder. My one problem at this point is a nameless cockerel that is very stubborn. I spend their free range time taking him out of the brooder with him kicking and screaming the whole time and putting him down outside. He immediately makes a beeline back to the brooder. I hesitate to close the screened door, blocking his access to the brooder because the other chicks like to come and go. So now I park my chair in front of the doorway and he spends his time figuring out how to dart around me. Well, at least he's moving. Kinda sad really that these birds can become so conditioned to being raised inside, discouraged from moving around, that it frightens them to do anything else.
