Several times I have found my bantam rooster on his back. He can't get up and the first time I thought he was dead. One time he was in the snow and I thought he was dead. Today he just squawked till I went looking for him and flipped him over. Is this normal? Are my bigger chickens tipping him over? One day I nudged him out of my way at the doorway and he fell a foot or so and landed on his back so I wonder if he is just clumsy. He has gotten a little frisky with a couple of hens but in general I haven't seem him being very aggressive, or hens aggressive toward him.
