Should I try to watch and see who it is? I'd have to be sneaky, though--they come running when they see me, because I might just have snacks! Heck, if the garage door opens when they're out and about, they're guaranteed to get a handful of BOSS flung into the driveway... Anyway, are there likely to be any problems other than fuzzy areas on some hens? Egg production definitely isn't affected--I'm getting between 30 and 34 eggs a week from my 5 girls! Curry's back's been like that for a couple of months, I think, and I first noticed Quiche's thin spot 2-3 weeks ago, maybe longer.
Actually, it might be Souffle--her former name was Spurs, for self-explanatory reasons, and her comb's the biggest.
Edited because I can never remember how to spell "Souffle" until
after I hit "Submit"
