My little year old bantam Phoenix rooster is acting very dopey lately. He is kind of sluggish, his head is sunk down and his neck like he is cold but it's 70 degress out everyday almost now. He extends his neck to eat and he does drink and scratch a little. His tail droops unnaturally and his wings do on either side of him, too. I just don't understand what is wrong. We seperated him from the rest of flock for now. Any ideas? Thanks.
