Jerseygirl1 I'm sorry to hear about your tom.
I have a similar story with my 3 year old Royal Palm.
We had awful snow during winter and I let them out when it started to thaw for a bit if outdoors after so many months stuck in the coop.
Breeding season was starting to get under way and Thomas was servicing 4 hens in rapid succession.
When I came home from work Thom's was limping and had lost all of his chest feathers.
I don't know for sure, but I can imagine he could have kung-fu'd the chickens or slipped whilst mating (it was icy), I still have no clue about the feathers!
He seemed in discomfort when I checked him over, but no swelling or breaks could be detected and the area in question seemed to be his hip.
I helped him off the roost each morning, he managed to get up there by himself until later in the summer when he chose to sleep on the floor of the coop.
I have read that round perches don't do the ligaments any favours and that wide square planks are better.
I don't know if that's true or not.
His stride is not that of a young turkey, he doesn't seem to rotate his hip properly. But is in no pain.
Thomas is now a proud dad as 2 of his hens produced flocks of poults. He spends all day with them walking miles and actively brooding the babies at night too.
