Hi, has anyone had the problem of a dog eating chicken poop? Mine does and I wonder if it is causing him to be sick? He hasn't had diarrhea or vomiting and seems to be healthy otherwise. But lately I've noticed he has been eating grass quite a bit and sometimes I hear his stomach going crazy growling. If the chickens had some sort of parasitic worm, could he catch it from them? My pullets are 3.5 months old and have never been wormed.
