Yes, that looks like frostbite on both feet. It can take days to weeks for all the damage to become evident.Oookaaay. So it's escalated. The swelling has gone down, but her toes are dying.
There is no feeling on the black parts. Frost bite? I would think that the swelling might have cut off circulation and caused gangrene to set in, but why is happening on the good foot too? does frostbite take days to become evident? I don't know much first aid. only that required to get someone to medical personnel, so I have a whole lot of questions what and why and no answers. Confirmed that black areas are uncontrollable, sessile, and have no feeling; shriveled. and it's spreading, faster on the swollen foot than the good foot. The swelling has gone down tremendously, though still evident. She is waving the foot around in the air as if she is trying to get it to move. same chicken as before, pullet, some kind of laced breed that has feathered feet as chicks. Foot was swollen 4 times it's normal size. now barely twice.
I guess, I'll have to put the hen down, but I want to know what it is, and if I can cut the toes off and her be fine, and how to stop it, etc... I don't want her to suffer, and I do want to fix her up but I don't have an inkling as to what this is. Suggestions, ideas?
It's hard to know how much of the foot and toes she will lose.
I would not cut the toes off, let them die off and fall off on their own.
You may not need to put her down - it depends on how much time you want to invest in the healing process. It's going to take a good while for that to heal.
