We seem to have lost my fav chicken, Doodle, as of 24 hours ago, when she didn't come home to roost. Now, I have 2 other chickens that are limping, holding their legs up like flamingos. Both legs/feet look and feel perfectly fine and joints feel stable and not swollen. No sign of bumblefoot. I've separated them both into a dog kennel with warm hay, feed and water. I noticed yesterday, also, that they had clumps of moldy food in their feed bag (grr). Think they just helped fend off an attack and possibly strained their legs or is something else going on here?
