My hen has been setting for 25 days now she is still holding strong. She has 2 eggs left and nothing had happened I don't know what eles to do. Will she give up if nothing hatches? I was wondering if I bought hatching eggs and put them under her would she sit again for 21 days? I have such bad luck this time going around due to weather but I thought if she would continue to sit since she is not giving up if i brought her into the house to sit on the eggs? Plz any advice would be great if she would contine to sit for another 21 days I can have hatching eggs here in a couple of days.
