Dot is still broody. I don't put my chickens in a broody buster or anything like that. I just keep them off their favorite nest and within a few days they're broke I tried the broody buster with Spice, a Mille Fuer hen and she went crazy. HATED it. So I blocked off the nest box and she went around like a normal chicken but still made broody sounds. Dot doesn't walk around. She sits in front of the nest and pretends there are eggs under her.
Also, she is not mean when she is not in the nest.
