Our 23 week old SS Hamburg cockerel has been crowing for a few weeks, maybe a month or 6 weeks now, and I have noticed several times that when he flaps his wings very hard before crowing he will stumble around a little and list to the side like he is drunk! He doesn't do it every time, but I've noticed it 5-6 times over the last 2 weeks. He comes out of it within 30 seconds or so and seems fine. I'm wondering if anyone else has noticed this with their roosters or if it might some sort of ailment that is causing this with him. Thanks!
