My hens and roosters (2) are coming of age. The hens seem really upset when the roosters try to mate. Will this stress them out and delay laying? The poor things flap around while the rooster has them by their combs. One hen had her comb partially ripped. I have to say that it upsets me too to hear them squawking. One of the roosters is leaving soon because he is mean and has started attacking the other rooster, but I may just get rid of both of them because I don't like how they are treating the ladies.
