I rescued some young chickens and noticed a couple of them were not walking and eating. I picked them up and examined them and found that their feet had what looked like mud and crap caked on the bottoms. I brougth them in the house and soaked their feet in warm salt water to loosen it. Some started to come up, and then the scales started to come too. They were no longer attached, and their feet are very sore where there is no scales. I can't get all the stuff of the feet, I soak them twice a day and slow work on them, trying no to hurt them. How long does it take for scales to grow back, and has anyone had this happen to their chickens? I would like to know what could cause this. They do smell bad, so I am keeping them ina clean pen and soak with salt water and Betadine.
