Yesterday my good neighbors! two cats killed my pet bunny of three years and my prize Australope Roo and 4 hens in 30 minutes, if that was all it would be enough, but this morning out of the barn window came one of that one cat with a chick. Not sure what to do, but it may be time for a dog that is quite and will gaurd my chickens. I have had it. This was the 2 nd replacement of egg layers.....Help?
