Between them they have hatched out over 30 chicks and not one of them is taking responsibility for the chicks they just keep sitting and sitting some of them on NO eggs. I have tried putting one alone with them moving eggs taking eggs moving broodies you name it I've tried it. They just sit when a chick is born they just leave it to die if I didnt take it and brood myself. None of them are hatching in a clutch either just one a day sorta thing like they were laid. they have been broody for months and just sit and sit and SIT!!! Any advise on how to get them to first off hatch properly and then to take care of the chicks?
