This rooster is now 20 weeks. At 6 weeks he was bitten in the butt by a coyote. He crawled out of the woods 12 hours later with his wounds covered with maggots. After 2 days of war on the maggots he started getting better and 2 weeks later he was in full health with just couple of tail feathers missing and integrated with the flock. About 3 weeks ago he started to lose the rest of the feathers and now he is completely tail less. There is no evidence of any pecking,at least I have never witnessed any of our other roosters or hens even paying any attention to his tail and we do spend fair amount of time with or around the flock. (our flock was hatched in June so all 9 are about 20 weeks old). Not that it matters but is he going to remain tail less? Another questions. We are getting addicted to chickens. With 4" x 8" chicken coop and 7 nesting boxes, how many more can we get without overcrowding the coop? We now have 9. Thanks for helping.
