We put ceramic eggs out last night. I went to the coop about 11. No eggs, but while I was down there my barred rock and white leghorn went into the boxes. When they came out the barred rock left an egg!!! They are 21 weeks. We have 8 egg layers 19-21 weeks, different breeds. Is it unusual for them to lay while you are there? Also, it's tiny but it has a nice hard shell. Will Her eggs get bigger?
