Chicken and Egg Responses
On the subject of chicken egg fertilization -
following on from another query i've just seen.
If not all eggs are fertilized - are chickens aware of which are
thus protect them from us egg-pinching humans or is it just a
matter of luck?!
For the most part, chickens have no idea which ones are fertilized and which
ones are not. They will sit on unfertilized eggs and protect them.
