I think, I hope, I have shut the boogers out of there tonight. It really irked me when I checked on the chickens late last night and saw all the rats. I have an old chicken house and the old man who owned the house before was not doing any repairs. Instead of replacing panes of glass, he would just board up the whole window. I have been fixing it up a little at a time. Anyway, the plywood overlapped the window and gave the rats a nice little inner wall to nest in. The were coming and going out of the window. There must have been a dozen of them in the wall and they all started bailing out the window when they saw me. Most it seemed were babies. Lately, it seemed as if my chickens were eating twice their normal amount and I found a bag of layer pellets torn open. So, today, I stapled chicken wire to the window (for now), ripped the plywood out of there and then stapled heavy plastic up. I put all of the feed into the plastic trash barrel and have been thinking about sprinkling cayenne pepper on the layer pellets. Birds seem to like it and the rats should have one hot tamale.
