I have 4 one year old chickens that lay 3 to for eggs a day. However, ever since I merged 7 of my new 10 week old pullets, egg production has dropped. The cause of this is THE YOUNG DING DONGS WONT STOP CRAPING IN THE NESTING BOX! I have to clean the box out almost every day! The big ones hate the little ones for it and fight all the time. If i could only figure a way to get the little suckers to stop roosting in the nesting boxes I would be all set. Any suggestions?
