Hi, I have had my first chicks for 2 weeks now in a brooder. They are 4 weeks old and so much fun. I don't know about chicken behavior though. There are three silver laced wyandottes and three ameraucanas. One of the ameraucanas gets in all of their faces and stares them down. It chases them and jumps on their backs. When I open the lid and they run over to see me it chases, jumps on them, and gets in their way. When they jump up on their perches/roosts to make their way up to jump on my lap it tries to jump up and pull them down. Is this just establishing a pecking order or so I have a bully on my hands? Thank you!!!!
