One of my roosters, Fred, is about 15 months old. Whenever I approach him he’ll try to find a corner, beside a bush or a corner of the coop and crouch down and make a screechy noise. It reminds me of a dog that’s been mistreated. I’ve never EVER hit or kicked or anything like that to Fred. Once I say his name, he’ll look at me and stand up and act like himself. I’m very hands-on with my chickens especially Fred. He’s spoiled. He’s not aggressive, he’s not being bullied by other roosters, he’s the dominant rooster of his flock. This behavior started a few weeks ago, and I can’t figure out why. Any ideas?
