Hello all! I am very new to the broody hen/natural incubation period. I had a game hen start to set on eggs about 12 days ago. Over a period of two days, she had 9 under her. (obviously not all from her). On day three, I added a 10th egg. On days 4 and 5, she switched nesting boxes and was sitting on air for a bit, and twice I moved the eggs underneath her. The second time, I put her in her own crate, in a separate area, with her own food and drink, and only one nesting box for her. She has been sitting on them consistently now for about 10 days. Today when I went out to check on her, she had literally taken one egg out and it was brought all the way to the door entrance somehow. It was nice and cold, so at some point, she decided she didn't want it. I did crack it open, and it was NOT fertilized (but was the first double yolker that I have seen personally from my hens). She is still sitting on the other 9. So. My question is, and I think I know the answer to this... Would she have any way of knowing/realizing that the egg was not producing anything and kicked it out? Or would it be because I physically put this one under/beside her. I have yet to try to candle the eggs, and it is possible that she is sitting on 9 UNfertilized eggs (yes, we do have a rooster, so it is a possibility...I'm not THAT new to this lol), and will be sitting for no reason soon. I'm just enjoying this natural process, and can't wait to find out. What are your thoughts on trying to candle to see, or just waiting to see what happens? Thank you to everyone here who has posted so many wonderful things. I have been able to do searches for nearly everything/every question that I have had. I wasn't able to find anything about hens removing a selected egg, but that doesn't mean it isn't there... Thanks!
