Recently a rooster I use for display at field days got stupid and got into a dogs mouth. Dog clamped down a couple times pulling some feathers, caused some deep bruising and perforated a lung. Bird is coming around on all damages excepting for feather loss. At time of attack most of the major flight feathers were no longer green although sicle and body feathers were still coming in. One of his tail feathers that was lost earlier in molt while green is in the process of being replaced. If I pull the damaged feathers that remain, will he regrow them or will I have to wait until next fall for damaged feathers to be replaced? Images below show bird in question. Last year as cockerel. Just before attack. Two days after attack.
