This is exactly what we needed to read. Question, we have taken our granddaughter’s neutered 1.5 yr. old Blue Pit while she is participating in a long-term rehab program. He is wonderful with us, our grandson, and great grand 
son. I am not sure how he is with other dogs as we had him and our old guy before we had him put down due to illness and old age. he was not aggressive with him so, I should get to my question: how do you think he would do with chicks? Is he too old to introduce them or, based on what we know about him, do you think this might work?
