I was just locking them up in the coop at 8:30 and there are always some minor scuffles until they settle in. My "nice" splash cockerel went after 3 pullets, just to bite them. As he was hanging onto her tail the younger, fiesty cockerel went after his tail. The splash flew upward and hit his head, hard, on the ramp. I heard it. He flopped around unable to lift his head off the ground, doing the dying chicken flap. I thought he broke his neck. He flopped around some more and was able to get into a sitting position. He is moving his head around, dazed. Maybe he just knocked himself silly and is stunned. His breathing is returning to normal, not frantic panting, but he's just sitting there, whimpering. I can just see that little silkie brain swelling up. He has a very vaulted skull. So, what should I do? I'd like to put a little ice pack on his silly little silkies brain but know that is impossible. My 1st instinct is to wait it out and see how he is in the AM. But...should I bring him in to watch him? Baby asprin? V & E? ice his little bird brain? Jeez!
