If it's only one, I'd just keep an eye on things. She could have bent it weirdly and then chewed it off because it was bothering her. If you see more, then you'll have to delve into her diet, environmental stress, possible infection, etc.
My girl flew to me yesterday and dropped a feather. I gotta say Iβm a bit concerned. Looks like she chewed it off, had a bit of blood on the end. Strange because sheβs always happy, singing, whistling, talking and always wants to be with me. Any ideas what to do to prevent this from happening.
cheers, Steve
I've not been in a similar situation before but it sounds like you did everything you could. You cleaned off his feet and it doesn't sound like he had chance to ingest any, so hopefully all is ok!
Alfie doesn't like going on the floor very often so I always move anything breakable or destructible on to the floor. If he does end up on the floor he's normally quite cautious and moves around slowly enough that I can move anything out of harms way.
