it won't hurt them to have their feet and leg feathers look a bit dingy, but it is probably unnecessary to wash them this early. If there's poo in the feathering, just wash that portion and blow them dry on low so they don't catch a chill. I use liquid Ivory body wash on mine, but for the spot washing I don't worry about doing the vinegar rinse.Ok peeps (pun intended), I have ventured into Silkie territory and this is my first cochin breed. I have read multiple sites but only one addressed actual chicks. The owner stated that every night she washed her chicks legs. Now I see why! Holy Moly I want to wash their legs so bad it's making me crazy! is it too early? I've never bathed a chick or chicken before and although I now know from reading, all about the dawn, the vinegar/water rinse, etc... I'm afraid they will catch a chill or I will blow them across the room with the blow dryer (LOL). Granted these guys are probably a good bit smaller than the rest of my flock at the same age but I THINK I have two that are a few days old and two that are a week or so? We have Barred Rocks, Buff Orpingtons,Australorps, Delewares, and one Golden Comet..... As you can see... never had any need for washin' legs, lol.
