I live in AZ so the soil is very conducive to ants but this is ridiculous! Went into the coop last night and there were literally thousands of big red ants inside and outside the coop. My three week old chicks were doing their best to eat them but couldn't keep up. I have added DE to the pine shavings but it doesn't seem to phase them. Please help! I know I have to be careful not to poison the chicks by using something harsh but something has to be done!
