One or more of my 12 week old chickens is having loose stools. I have raised them organically and want to sell their eggs as organic. I think it's the silky roo with the problem but maybe one of the other girls has it as well. For 13 of them (with only one rooster) it's not that bad but I would like to get a handle on it. At this point, they don't get any vits but maybe I should put some in their water. Any suggestion but still be organic???
