I have 10 RIR, 23 weeks old. We got our 1st egg 8/29 on the floor of the coop not the nesting box. Next day there was no egg. Yesterday morning I found an egg again on the floor of the coop. This morning there was no egg. However, later this morning my big RIR was singing her song, all the other chickens were running in and out of the coop. When I checked the coop I had a chicken (not sure if it was the one who layer) pecking in the nesting box, when I opened the box I found she was eating what was left of an egg. How do I stop this. They had been eating start and grow, we just switched to the Layenna pellets. Are we feeding them the right stuff? We are new to raising chickens and eggs. Any advise would be helpful.
