How in the heck can I deal with these pests??? They are taking over my farm. My husband set bar bait in places where my chickens can not get to it but of course one of my fav hens must have found a poisened mouse and ate it up. Now I'm sure I won't have her much longer....I don't have food out at night except for the pullets which seem to eat all night long in their heated pen. The grain is in a metal can which they can't get into. I know being a farm they will just be around but it seems to be getting out of control. Is this just the life of a chicken farmer?
