My chickens are allowed to roam around the farm. They were using the nesting boxes for a while, which have wooden fake eggs in them. There are 4 boxes, about 12wx12dx16t in demensions. They are built in a 2x2 square. The chickens have taken to laying their eggs in different areas of the barn causing me to go on egg hunts. After I locate the area and remove all the eggs that are left as some are broken and eaten. They will sometimes stop laying in that area and find a new place to lay. I would like to get them to start using the nesting boxes again and then work on the egg eating issue. Given that it sometimes takes 2 to 3 days to find their new nesting place, usually by hearing one cackling while laying, I can't combat the egg eating by getting the eggs out early. What can I do to help resolve this issue?
