I have a 2 year old roo (he's a house chicken and has always been alone which means no flock) and today he's been quiet. He crowed a few times this morning but that's it. He eats so little and feels very light. His comb is black-ish (which has happened before. The vet told us it was because of dehydration) but he isn't drinkin water. This behaviour has only been going on for a few hours since it's early noon but it's making me anxious. I have an inkling it's because lately I haven't been allowing him as much into the house as I did because my parents threatened to give him away if I do. So he's been spending more time out in the balcony. Any advice? I'm getting worried.
