A couple weeks ago I noticed two of my hens toes lookes red and swollen. It didnt look too bad. I thought maybe a bigger/flatter perch or the cold got them. Usually I don't see her toes cuz she sits on them but today I saw them. Oh my gosh! She's missing two toenails and the toes are swollen still. The far outside toe that is kinda red is what the two stubby toes looked like before I noticed missing nails today. That explains the bits if blood on the perch. Any ideas of whats wrong, happened or what I should do? She doesn't seem bothered but I can bring her inside my house if need be. Any help is appreciated.
