Hi there! I saw some silkies today and have a question concerning the roo's feet. The hens & chicks had feet which looked like regular chicken feet (does that make any sense? it just sounds weird!!) except with LONG toenails, but the roo's feet and legs looked like something out of a sci-fi movie. They were lumpy and nodular looking, like burls or gnarls in an old tree. Is that a genetic trait, an aging trait, or a symptom of some disease or other abnormality? I am really curious, and would like to have an answer. All you silkie lovers/owners/experts, sound off here! Thx in advance!
