I know I have rats in the ground under my coop. I've seen one at least and there is a mound of dirt. I have tried to flood them and one came out and there I was running around chasing it like a crazy lady with a pitch fork. Needless to say it got away. I know if you see one there are always more. Ok one morning this poor little chick was just sitting there. AUGH...
So sad, when I picked him up, one of his legs was torn off. Heartbreaking... I culled him. But now this morning there are 2 chicks and 4 ducklings missing. NO trace what so ever. Can rats eat that much and not leave a mess? I've tried traps with no luck. I can pit it under the porch of the coop. when I started taking the feed out at night they started on the babies. I think a measel would be the only other thing that could get in there, but don't they just kill and drink the blood mostly, so there would be a mess? If a snake ate that much he wouldn't be able to move.
