I found 3 first eggs from my almost 6 month old chickens that I raise from eggs last Saturday. I decided to clean the coop and put new shaving on the floor. The next day, I found 2 eggs, 1 of them cracked. None Monday, then today, I found 1 egg in the run area. The second egg was found in the coop where there's no shaving. I also notice many chickens sleep outside of the coop. I wonder if pine shaving is the cause?
