I have a hen that is laying eggs and she is about to get broody. she has laid about 6 eggs already. Now I have some eggs in the incubator also. I want to wait untill the eggs hatch and slip the babies under her for her to brood. Will she still accept them if she has been sitting on the eggs for only about a week. Does she have a sense of time and say its not time yet to have babies and ignore them or will she just get up and leave the eggs?
