Hen pecked out of nesting box..

[RuralAmy]

Hey all! Most of my new ladies are laying now. When any of the new girls are in the nesting box, one of our older hen goes in and pecks the new chicken out of her nesting box so she can lay. She doesn’t lay in the same box that she pecked the little girl out of. I’m worried this will create fear for the new girls to continue laying. The older one who does this only seems to do it when she needs to lay. Even if a new chick comes into the nesting area to lay while she’s in there, she will peck them out. She’s bottom of the pecking order for the older group and is the only bully to the new group. Thoughts or ideas?
