The rooster is a year-old standard polish. Here is a pic from before a coyote took his hen- he was jumpy and energetic and vocal-a typical rooster! However, his hen died about three weeks ago. Since then, he's become very despondent. He sits in one place most of the day, with his head and tail drooping. He sleeps on the ground, not even bothering to fly up to the perch with his buddies. He never crows. He only moves to eat a little bit.He shows no interest in the other hens. The other rooster in the coop, once a friend, now pecks at him, and pulled out most of his crest. The poor guy is miserable. Is there any way to cheer him up?
