I don't know how or when it happened but at least 8 of my 10 chicks have little poop balls on their toes. I'm so mad at myself for not noticing it before it got so bad. After spending at least an hour picking concrete like poop off of the toes of my little poo machines and then having to soak the pasty chick I've come to the conclusion that the brooder I have is too small. The babies are 2 weeks old and perhaps an addition would be in order. It is made of wood so perhaps cutting a small hole in side of the box that would lead to a screened in area for them would be a good idea. I should also mention that it is in an unheated garage . Are the chicks old enough to know that they need to go back in to warm up? Funny , never had this problem the first time when there were only 4 chicks or the second time when there were 6.But this time it seems that 10 is toooooo many for my little homemade brooder box.
