Today my son and I were in the coop where we have 44 12 week old chicks, various breeds, most from Meyer Hatchery. They are growing nicely and my son noticed that one of the bantam cochins feathers were changing colors. SO I caught him to take a closer look, the colors are so pretty, and I noticed his feet looke really weird, but they are feathered and so I thought maybe that is just what they look like, so I caught another one and another one, I turned about 5 or 6 different breeds over and the bottom of there feet all looked puffy for lack of a better term to describe it. No open sores, or bleeding, nothing that looked like anything other than puffiness. They are in a coop with pine shavings and oak leaves on a cement floor, but the bedding covers the cement. It has just turned pretty cold here within the last 3 days. They get fresh food and water everyday, I weaned them off of the medicated chick feed, but they are still on chick crumble. Is this normal, and I know you will ask for pictures, but I don't have any, and no way right now to put them on this site. I tried googling it and well, I'm not even sure what to ask to prevent from getting some really weird responses that have nothing to do with chickens Any help is appreciated.
