Ok good to know, this should make it easy to set a routine for both you and her to help her out being her first time. Pick a time and if she has not wanted to come off by then each day remove her and put her outside. If she has not decided she is done in a hour, bring her back in yourself. The eggs will be fine. I would also not turn on a heating pad while she is out, they are in more danger of getting too hot then getting too cold. If you want to you can just cover them over with a blanket or towel. If she seem lethargic while on the eggs do not panic, she is actually in a trance while sitting there. She will have enough sense about her to turn the eggs, or shriek at you if you walk by but she is not going to be actively shuffling about or talking. If the eggs are good, you will hear her start softly talking to them once they have made that internal pip. If you are lucky and sit beside her then you may even be fortunate enough to hear the chick peeping back to her.She’s a house broody (and she keeps me company) she likes YouTube videos, like Jaffar does.
