I have 3 hens that are about 18 months old. I am adding 10 chickens to the coop. I have enlarged the coop and have purchase 4 new plastic nesting boxes. I no longer want my older girls to use the old nesting boxes. In the summer the original nesting boxes get very hot here in TX. Now that we have added on to our coop i have a much better place for nesting boxes that will be cooler in the summer for them all. Should I just place pretend eggs in the new nesting boxes and let the girls check thing out before I close out the old nesting boxes or should I just close them up and hope the girls find the new boxes to lay in? It probably would have been easier if it was a completely new coop but we decided to turn are run into a big coop and open up the old coop into it. My chickens have about 1/3 of an acre that is fenced in for free ranging they are not stuck in the coop unless weather is bad. It's a lot of changes for the my older girls so I want to get them used to the run being their new coop and the new nesting boxes before I introduce everyone! Any advice would be appreciated.
