I have a hen that has been setting on eleven eggs. 2 of them hatched 3 days ago. We went out this morning and they were dead. I don't know what happened. Where we live we have fire ant problems. Of course the dead chicks were covered with ants. I don't know if the other 9 eggs will hatch. Yesterday was 21 days. I'm worried now that the ants will be in full force now and kill the new chicks if they hatch. Another question: I haven't seen the mother hen getting off the nest since the chicks hatched. Her comb is not red anymore. Do I need to take her off the nest and take her to food? She had been getting up and eating before the chicks hatched. Any advice would be appreciated.
