Why Hens Leave Fertile Nest Eggs Unattended

Chickens never lay more than one egg per day. If the eggs are not collected, and a sufficient number of eggs are allowed to remain in the nest, the hen may stop laying eggs and start brooding.

When the hen leaves the nest after laying an egg, it cools which suspends the development of the embryo inside. If the temperature remains between 45F and 65F, the embryos will remain viable for as long as two weeks.

When the hen becomes broody and sits on her eggs for three weeks, all of the eggs will hatch at about the same time. This is why it is normal for the hen to leave the nest after laying.

Remember, not all breeds of hens will sit on eggs…ever. However, some breeds have very strong tendencies to become broody, or be inclined to incubate eggs.

Here are a few common broody breeds…

•Buff Orpingtons • Silkies • Cochins • Light Brahmas • Dark Cornish • Buff Rocks • Turkens •Buff Brahmas • Cuckoo Marans • Cochin Bantams • Cornish Bantams
