I have an approximately 7-month-old Brahma cockerel who has been just not quite right for about two or three weeks now. Symptoms: He walks a little and then lies down, leaning forward. He looks like an old man with arthritis when he walks. When he turns fast, he stumbles and wobbles a little. He won't scratch. He will dust bathe, but just lies on his side in the dirt, again not scratching. He walks slowly and runs slowly, again, lying down every so often. He will lie down to eat. Poop is normal, he is eating well. He is a little thin, but not unusually so for a growing boy. I have been giving him extra vitamins and extra protein. He doesn't roost, so didn't jump down and hurt himself. Has anybody out there had this same problems? Any ideas?
