Joe Black, our pet rooster, has been depressed with tail down and not eating well for the past week to ten days. Short history on him, he used to be our Alpha rooster, but he had an injury and was confined to a pen for several weeks. When he recovered and went back out, he lost his status, and was unable to continue free ranging without being beaten up by the other roosters. I thought, that he was just depressed, didn't reallly think about him being sick, we have had plans to try to reintroduce him to the flock later, and he has been in the tractor in the barn for the past few weeks, and has been fine. Anyway, today at breakfast he was sitting down and there was copious greenish diarhea everywhere. I have no idea what to do for him! Anyone???
