Why does my 7 month old bantam rooster crow while doing circles? He looks like a dog chasing his tail. He turns his head to look behind himself, starts to crow and then just like a twirling ballerina he does circles till he stops crowing or gets dizzy and runs into the fence. He has been doing this for about 3 months now. Background on him is his pen sits next my other one that has 2 pullets and 1 rooster in it. This one was too mean and has been seperated and secluded for months now. He also crows NO STOP pretty much all day which at times gets my other rooster going and then it's just a backyard frenzy of crowing wars. I'm perplexed by this behavior and can't find any info online about this. Please help!
