I have 3 roosters and 2 hens. I know that this ratio isn't very good, we originally had 1 rooster and 2 hens so we thoguht that we would get 2 more hens to prevent problems for the two hens, however the two "hens" grew combs and have started to crow. I've heard that having this many roosters causes them to get into fights with one another over the hens, potentially leading to serious damage to them, however this doesn't seem to happen. The oldest rooster ( I assume he is the alpha because he generally is the first to respond to any trouble and because he generally leads the flock, as well as both the hens crowding around him) tends to ignore the two other roosters trying to mate with his hens, and doesn't attack them either. The two younger roosters not only tolerate the other mating with the hens, but actively co operate in trying to mate with them(usually when only one of the younger roosters try to mate with a hen the hen chases him off). The other day I also saw one of the younger roosters preen the oldest one. I'm not too sure whats happening here, why the oldest rooster would tolerate this behaviour, and this is my first flock so I don't have any prior expierience to this. Anyone know?
