since i did my new coop i have not had any mice. i made sure there is not a place they can hide at all and that has helped. plus my girls have been known to hunt mice. and our cat used to be a street cat so is very good at hunting. so with all of that it means i am not dealing with any mice. i hate mice. gary momo is so cute. she has gotta be one of the best broodys out there. any idea how many she has hatched out?
