Some people wants to know can they get 10 lbs chickens out of the cornish chicks. I put some on feed for the first time and here is a few pictures of what I got and they are big enough for Xmas. The roosters will weigh around 13 lbs live and dressed out around 10 lbs and the pullets dresses out between 7 and 8 lbs and these cornish weighed 6 lbs live weight at 6 weeks of age had no problem with them at all I just dresses out 7 the first day do to the weather and I like what they turned out. I will never butcher another breed of chicken unless I raise it. These cornish are under 12 weeks old and I fed out some RR and at 12 weeks they were around 4 lbs live weight.
