We came home today and one our hens were out in their run after dark. She was on top of their feed bucket looking at and pecking on what looked like a broken, fragile egg. I assume on of them laid a nighttime egg on top of the feed bucket or something since there is no way to roll it out of the coop onto their feed bucket unless they carried it up there. We live in city and neighbors have motion sensor lights and such so I don't know if this is why they came out. When we were out checking on them some of the other chickens flew out and started eating big cockroaches and crickets. Should I be worried? I thought chickens stayed in their coop at night. Our chickens routinely go in at dark and I have never seen them back out before.
