Oh my god those poor babys, that is horible, very cureible but horible.
the firts baby is dirt build up and be careful pulling that off, soak her feet in warm water and then rub off gentaly , that is so attach it can make her bleed., I am going to say it, who ever you got them from does not care for them, that is poor health poor takeing care of. I am sorry.
I am glad you got them and that you are takeing care of them, poor babys.
also what could help for scaly leg is 2 of these, vet rx, and superior 70 bay rum, if you use 1 or the other not both, and then cover in vasaline.
we use these as a preventitve against scaly leg mites. we had gotten a hen about a year and half ago, and she had that and we used these 2 and they were gone.
we used 1 one day and the other another day.
