No, I use dog nail clippers, I'd need to restrain him to file them, and I'm just not going to do all that. They'll smooth out with digging and scratching, imo
The feathers will grow back after she molts. It's really up to you what you want to do, with having more pullets that he'll be able to breed you may not need saddles. I had a hen a few months back that my roo didn't breed much (not to my knowledge anyway) and her feathers didn't look terrible...
I put them on my roos favorites right away, I have a couple ladies he seldom breeds, but noticed 1 he started breeding more frequently so I put a saddle on her last night
Both- it does make them look ratty, but once the feather barrier wears down he can do real damage to their skin, punctures...
