We had one like that - she was even a big meanie on the ride home. I had to hold her most of the way. We started brooding them in a kiddie swimming pool. Once we got them home and into a bigger space, she seemed to settle down. Then a few days later, out of no where, she started up again - being very mean. Since I only had one light for our brooder, I couldn't separate her totally from the flock, so I put a small laundry basket in the kiddie pool with her in it. Gave her own little habitat for the night. I put her in with the rest the next day, and she's been a sweetie ever since. We call her Gabby, because her voice is so deep compared to the others - I hope that doesn't mean that she's actually a Gabriel.
