For the past 3 days, I've declared war on the rats that thought they were going to take over my coop. I've now got the upper hand. I had tried rat traps, baits, etc. Nothing was working, and they were worse than they've ever been. I turned dirt, and flooded everything. The first day, about 12 rats came out. I was able to kill a few, but really could have used an extra hand. It's not easy to dig, flood, and whack rats, all at the same time with only two hands. They're FAST too.
Later on, Dh went out there, and I had him cut all the tree limbs that were overhanging onto the coop roof, and inside the electric fence. Dd #1 helped guide him, and they dragged the limbs to the burn pit. While they were working, a couple of the rats were trying to get back to the coop area. Dh killed them.
Yesterday, I dug, and flooded again. Nothing. No tunnels, no rats. I know cutting all those branches has had a great impact.
Today, no droppings in the feeders, no tunnels, no signs of rats anywhere. The chickens seem happier too.
