Hi All, I'll start by saying that this is my first attempt at raising chickens... and despite my attempts to read as much as possible, there's always so much more to know . I purchased 8 cornishX and, 2 RIR, and 2 "pan fry special" chicks from Orescheln's 3 weeks ago as an experimental meat bird flock. I am trying to determine if my 4 "colored" birds are cockerels or not. FWIW, I think my 2 pan fry's are barred rock or a cross of such. Is it safe to assume that if they have nice little red combs at this age they probably are? I can try to post pictures later today. Behaviorally, I think they are little roos... they love to boss each other around and are starting to pick fights. However, I have read on this forum that young pullets will do that too!
