Please help. Our LF Blue Cochin Hen is having a bit of a problem with the top of her foot. Can anyone help us identify what exactly is going on here? It doesn't seem to bother her right now but I have noticed her "waving" that foot (like a small child waving hi in an up and down motion) previously. It is only on the one foot, her skin seems different looking in that spot. (she does not seem to have anything else going on in any other areas on her body and she is eating and laying) We have 5 other hens (one other is another LF Cochin) and none of them seem to have anything skin/foot/feather going on. We have blue kote, should we apply it? Please help us identify what is going on and if we should be worried. Thank you in advance.
