so we FINALLY got eggs. We are beyond excited!!!! However, our chickens are laying their eggs on the ground, and they have made an indent in the ground to do so. This morning there was an egg on the poop board (broken) as we think they laid it while they were roosting. Is this normal? The two that we have are uncommonly large -- is it possible they are too big for the nesting boxes we built? (12" x 12")? should we build one a little larger for them? Advice please!!! Thank you!
