I saw an ad on craigslist for hens/pullets hatched last year. They have pictures of some of them. Does this hen's legs look normal or are they scaly looking? Some of the other chickens did not look like this, but others had legs that looked like this or not as much stuff on the legs - anyway this hen's legs look like strange looking stuff. Am I not seeing correctly and her legs are normal? This is for learning purposes: to see if I can recognize something wrong or not. If the legs are not normal, could anyone explain what is wrong and what would need to be done.?
