I have a BO chicken that has been broody since last saturday. I had issues with my incubator so I took by serama eggs and put them under her and took her mix eggs and put them into the incubator. (not that I need more chicks, I Just felt guilty since they had already been baking for 5 days) Now I have a sex link hen that keeps trying to take over her nest. She practicly sits on her. I was worried in all the fighting she would break a serama egg, so I took some of the mix eggs out the incubator. My question is since they have already been baking for over a week, will there be problems since she just started sitting on them? Also...Can I keep adding fresh eggs to the mix and just take the chick when they hatch so they she will keep sitting and hatching out more since she is already ahead 8 days of baking.
