Another brief update. I put a perch in the tree and moved his food bowl nearby. He was using the food bowl when I put food in, but I've also seen him appear to be more adept at finding his own food, so I've really decreased the amount I've been putting out. In fact, one day, I was walking to the tree to put more food in and he was following me. As I turned a corner, I looked back and saw he wasn't behind me. I looked back and saw him with a wriggling lizard in his mouth. He flung it and then retrieved it and appeared to be occupied so I used that time to put the food in the tree. Once I returned, he appeared non-plussed and walked onto the porch as if nothing had happened. I looked for the lizard and didn't see it. I felt up his crop and felt lizard in there. So success! (poor lizard)
Anyhow, despite some initial improvements, including him increasing his range daily, we had a major setback as well. Someone's dog was loose a few days back and wreaking havoc on the condo. It was chasing cats, it was chasing wild chickens (I've never seen chickens fly so high) and as a result, I had no idea where my baby had gone. We went out looking everywhere, but nothing. As dusk arrived, I was starting to panic because I know how my chicken panics at night with his need to roost. Fortunately, he came back but was missing tail feathers and seemed tired. I don't know what he dealt with or where he went, but he was beat. The next day (yesterday), he did a lot of sleeping on the porch so I was a bit more free-flowing with the food. Today, he seems better but still seems to be very cautious. He's been spending a lot more time hiding in bushes than he used to, but has also been wandering onto our porch a lot less.
So tonight, after he got himself settled on his perch on our porch, I waited until JUST after dusk. Then I rudely took him off his perch and put him up in the tree. He really panicked. He cried and cried and tried to get away, but I blocked his ability to leave. At some point, he kind of gave up and hopped onto the perch, briefly groomed himself and then hunkered down. I stayed in the tree for about 10 minutes waiting for him to fall asleep somewhat. After that, I slowly slinked away. I've checked on him once so far, and so far so good. So there is hope. He's definitely become more rooster-ish even though he still makes chick noises. He attacked my feet today, so my feet attacked back. Seemed to put him in his place. Anyhow, I've found this an interesting adventure and it will be interesting to see what happens tomorrow. I plan to cover the perch on our porch with a towel so that it's inaccessible and see if he goes into the tree on his own. Fingers crossed!
