I have 7 pullets that are 24 weeks old and still no eggs. 4 are Bantams, 2 Easter eggers and 1 buff orpington. I blocked off my nesting boxes with chicken wire for now because they were roosting in there at night. I have a 30 x 30 completely fenced off area for them to roam and the coop is inside the run. Any advice? I just bought some layer food to start using and slowing mixing in with the chick starter.
