i have a little sizzle hen and she had been laying eggs in her nest to set on for a couple days now,she was up to 4 eggs,well today i went out there to feed and water her and her husband and 2 egss were rolled out of the nest way away from under her box she lays. i am not sure if she did this or the rooster,the other eggs were still there i guess but i didnt check because i did not want to upset the nest. any ideas on this and why it happened?i am trying hard to get babies from this pair and it is not wroking

It could have been any of the chickens that moved them. They really don't need a reason. You could try to stuff them back under her if you think they weren't cold for long. If the rooster did it, you could separate them. If it was the hen, then she may or may not reject the other eggs. Hens supposedly can sense if an egg is not viable and may toss it out. To ensure a better hatch (if you know how to do it right), you could put the eggs in an incubator and hatch them yourself.
