I'm not actually sure were the ant hill is. Wish the fire ants built big obvious hills, but it's somewhere in my garden because thats were I keep running into them. I'll have to start shifting planters to see if I can find it.Good heavens! I didn't even think about that! I just assumed the ant hills were not in the run, but the ants were coming in to feast on egg and unfortunately live chicken. Yes, I would definitely not spread Amdro in my chicken run.
