My rooster Al is a Polish Bantam about 14 weeks. My son brought him in this morning saying he was acting "funny" and walking "funny". I put him down in the coop and he seemed to be fine. Now they are out in the yard and his tail is no longer upright. He seems to be walking fine, no blood that I can see. I have not been able to catch him to physically feel for any injuries. His tail is just down instead of the normal upright. Can they break their tail? Any ideas? What do I look for when I can successfully catch him?
