I was waiting for the answer to this, as mine are doing it with the shavings in the coop. Saw 3 eggs laid in the corner last week & when I went back later they were gone. Next day it was open with 6 eggs, that night gone. I ended up moving them to the nest box and finally taking them out. Now they are all 3 laying in the other side of the coop & I had 8 last count, but in the evening they are covered with chips & the next day some eggs are showing. I am going to let them go for now, as at least they are not laying under the coop in the dirt. I don't expect much, but we will see what happens. They could have about 10 eggs in there now, but today I could only see 6 & didn't want to mess with them.
