My husband and I recently bought a 6 acre plot of land that had a coop already built on it. We didn't think anything about it not being safe so went ahead and bought 13 chicks off of a friend to start with. We got down to 9 chicks so we put them in a cage inside the coop to see if that would help. We didn't lose any for about a week. Yesterday I went out to check them and there were two black rat snakes inside the cage! They couldn't get out after eating one chick a piece and then killing a third (they went into the burn bin to appease my blood thirsty husband). I am beginning to think we have a nest somewhere under or near the coop. There is a lot of brush and junk all around the coop that I am slowly working on clearing (husband works all day so it is up to me) but it is taking a lot longer than I thought. My question is, how do I tell if it is a nest somewhere and if it is how do I find it and get rid of it? I am down to five chicks now and I'd really like to avoid losing any more. I've done the moth ball thing the night before we found the two snakes in the cage with the chicks so obviously that didn't work. Any help would be greatly appreciated!
