We've found 5 now. They are never in the nesting box. One right under the roost, 2 in the coop, and 2 on the floor in the run. I have brought who I think is laying them inside for the night. All of our girls have free access to oyster shell. This particular girl has laid regular eggs. Maybe a month ago, she had a prolapsed vent. Got that taken care of and she has even laid regular eggs since then. Since we already give them oyster shells, what else can we do to get those shells hard again? Also, the soft eggs are always broken open. Usually we just find the shell. Last 2 days, they've just been opened, but yolk still inside. Ideas? Thoughts? ETA: She started laying in August.
