Well this is why I am interested in this....... I have my two sex links (about6-7 wks old) in a brooder up against the back of my house under a lean to. This is where DH and I sit and relax and where the dogs stay alot of the time. I let my pullets free range when I am home and they stay right in this area. When the chicks are out I will walk out of the back door to sometime see a squirrel running away! My dogs are a Pit Bull 115lb. and a boxer 90lbs.! So the squirrels normally stay out of the dogs wireless fence area. But something about the chick have them coming right up the where the dogs sleep???? Crazy squirrels! Should I be worried about this? Sorry about this long story.
