Ok, a week ago I lost three hens to a raccoon. I was told to use hardware cloth on my fencing, which I did. Thought I was safe, til the other night when the last two hens started squawking. I went running out in my slippers to find another dead hen, the last remaining live one, and the raccoon, all in the run. I didn't want to go back to the house to get something "substantial", so I grabbed the only thing laying there, a piece of birch tree limb. The coon climbed the inside of the run fence, and stuck his head out of an opening I had somehow overlooked. You know that arcade game, called "Wack a Mole"? Well I proceded to wack the crap out of the coon's head! Two good wacks and he dropped down and ran past the other hen and climbed another spot on the fence. All I could do was jab him at this point. Then he ran back to the first spot and climbed the fence, sticking his head out again. Again I wacked him, only this time I broke the stick. I was forced to open the gate and let him go. Here's a picture of the opening, and the repair job. It's about 4 x 7 inches. I picked three of these pullets up today, a cross between RIR and a White Rock, from Moyers. The last RIR I have is also in the picture. She has company again! You can also see the hardware cloth I placed around the perimeter, over the other wire.
