Hello , I am new to this. I have several different breeds of chickens and all of them were pretty easy to spot which were the hens. Having all the common traits... Then come my leghorns, whom are a whole different story. I was only able to get a picture of one of them. But the other one has a larger comb that was flopping over. Some days they behave as if they are hens and go into the croatching position. But they are also very dominant. They are at 20 weeks and haven't layed an egg yet. And the floppy comb one is getting quite vocal. ( you can hear it from the house but it's to quite a crow)... Any ideas?
