I have a silkie who goes into the coop and will pace back and forth but she will go to the wall and face it then jump up as high as she can almost hitting the ceiling each time for usually about two or three hours until she lays her egg. Is the jumping up normal for a chicken when their laying eggs? She does this every time. Ive been so focused on another silkie who is now finally eatting that Ive not paid much attention to my other birds and just heard her jumping in the coop so wanted to ask. Thankyou!
