Hi, My girlfriend and I are raising chickens for the first time. It's been really interesting. We are trying to figure out what breed or cross we have. They came from Sunnyside Inc in Beaver Dam, WI. The birds are only listed as "Dual Purpose Brown". We have 26 of them and they're 14 weeks old. Any ideas??? By the way, this site is great. We've never had chickens before and everyone has been soo helpful....THANK YOU.
