Okay, a few weeks ago,I posted about a broody hen, we got her 8 eggs, and she was doing well.....this past week, discovered a snake in the hen house, he had obviously helped himself to eggs...we have 3 left.......she has been sitting faithfully on them....either today or tommorrow will be day 21.....I am a wreck....I don't know what to expect....any advice is appreciated......how many days can it take hatch out eggs? I hate to not know.....I have done so much reading...and still have to much to learn....
