I was able to remove the hair, but the damage is definitely done. The foot is necrotic and drying up.
I'm hoping no infection sets in and the wound heals sufficiently to allow the poor little guy to fledge normally in another couple of weeks - hopefully, knowing no different and being so young, he'll be able to adapt right away and get around okay with the handicap. Poor little thing. :c Hoping he gets thrugh okay - how sad it is, so young and already damaged for life.

I suppose you just can't always predict these sorts of things.
