Hey! I recently hatched eggs from my flock. They're almost 5 weeks old now. I have a pretty diverse flock, but my two roosters are RIR. At this age, is it normal for the chicks combs to start turning pink? Some have and some have not. Of course I don't know which are male or female, but I'm hoping the light pink combs isn't a sign of cockerels! Thanks for the help!
