I have this mix of birds that I hope are all hens but would love any input. They are between 4-6 months old. No eggs yet and I think I have heard crowing but it could be a neighbor's bird. I am really thinking the black and white bird is a boy, it is the only one with a different tail. The white ones are leghorns the others are mixes of large breen birds. No clue on specific breeds. Please excuse the nasty bin, we had a bad rain and they played in the mud and poop then got it everywhere.
