OK I only have 4 chickens layin and I found a nest with 38 eggs in it Thurs, Now none of my chickens have been laying on this nest as they are all acounted for and I was not missing any. So I took them and put the clean ones in the incubator since I dd not know what ones were fresh or old and some have been there awhile. I woke up today and my husband told me my egs were hatching!! what they have oly been in there since Thurs evening! Yep sure enough one little bouncing baby chick! How did that happen???? I candled the rest but they are clear, I should be able to tell tomorrow if they are good or not.
