I have a hen who has made a nest. Last I looked she had about 4 eggs in it. Its still below freezing at night though, so I figure they won't even be viable. I've thought about ordering some hatching eggs locally. My question is, if I put a bunch of eggs in her nest for her to find next time she goes to it, will it help or hurt? I want her to start brooding some non hatching eggs before I put the fertile ones under her, so the the fertile ones do not freeze. But if she goes to the nest one day and theres suddenly an entire clutch, will she change her nest AGAIN???
