Not sure if I am posting this in the right area but I have four hens that are sitting on eggs. Two are sitting separately and two are sitting together on one set of eggs. Right now I have 10 hens and 2 roosters and they are all together. I do let them out of the pen during the day. - how long do the hens sit before the chicks hatch - once the chicks hatch should I dispose of the other eggs that didn't hatch - will the hens take care of the chicks or should I separate - will the other hens and roosters hurt the baby chicks Thank you for help!
