So I got 4 more chickens from a friend today. I know 2 of them are barred rock and the other two I'm not exactly sure on. I was able to get in contact with the original owner and she said one (the one with the red comb and waddle) is a dark cornish. The other one (has the black comb/waddle/legs) she isn't sure about. She said it may be a black sex-link crossed with an oliver egger but she doesn't know for sure as she had a lot of chickens and roos. Any one have any thoughts on what it could be? Also, someone else suggested that the one with the red waddle/comb was dubbed and that it may be a roo. I'm not sure what they're seeing that I'm not. Any help is greatly appreciated. Thank you.
