I have a 9 - 10 yr. old female pitbull that rescued me about 7 yrs ago now. She had a rough start, was tied to a post in a puppy mill and bred constantly for the first few years. A few chicks got out of the box on the way home and although I thought I retrieved them all one was still in the back when I left. I noticed my dog had been too quiet about an hour into the drive and found she had the escapee nuzzled into the sleeve on my jacket. The chick survived. Since then she will not let me into the back room where the brooder is alone. If I let her she will just sit there all day. If the chicks make a bit of extra noise she bolts to the room. When we come back from a walk the first thing she does is run down to check on her charges. It has to be frustrating for her, the brooder is too high for her to see in and I won't let her jump up. While I'm glad she is protective of the chicks I hope she calms down a bit soon. Anybody else experience this?
