I have an 8 month old Naked Necked rooster, he is not a purebred, but a mixed with the dominant naked gene. He has always been a strange little dude, he is quiet, doesn't bother the hens and spends most of his day on the roost sleeping, (but his crop was always full, and he has always been smaller and thin). As we thinned out our excess roosters and put the breeding hens in the pens, there are less bodies on the roost to keep each other warm and we have had a few weeks of -10 C at night and in the morning he appeared to be cold. He would sit on the roost with his tail down and his neck pulled in tight. I crocheted him a jumper and started to put him in our insulated garage at night. For the past week now he is sleeping more and eating less. I have to tap him to wake him up. In the morning I put him by the food trough and encourage him to eat, he'll fall asleep right there, I tap him to wake him up, then encourage him to eat again. His comb is bright red, it's not pale. The last 3 mornings when I come to greet him in his crate in the garage, he is dead asleep, I have to nudge him awake, it's crazy, what the heck is going on? He reminds me of a very elderly individual who sleeps all day, and when you nudge them awake , their eyes bug out like "what happened, what's going on!". It's gone from cute to concerning and I don't have a clue what's wrong with him, please any advice. I also wonder if he is possibly deaf.
