Hey guys new to BYC. I have 1 light Sussex (daisy) 1 bluebell ( Bella) 1 Nero (Nero) 1 speckeldy (Dot) Bella, Dot & Nero were brought home last February but Daisy was added in July. They're all 11 months old. Bella is top of the pecking order but when I went down yesterday Bella had jumped on top of Daisy pinning her to the ground and flapping her wings but not pecking. Daisy was just sitting tight closing her eyes. I shouted so Bella would get off. Is this normal? Thanks in advance
