brooding chickens

[lindat01]

I have 2 chickens that are brooding with 5 eggs under each of them.. I have taken them and there eggs out of the nest and put them in a cage by themselves with their eggs. Every time one of the eggs hatch I have a full grown chick and the mother seems to just sit on them and they die. Does anyone have any ideas of what I should d

Is she in a small space, or is there nay other reason she would crush them? If it's happening repeatedly I would take the chicks out of the cage and away from the broody as soon as they hatch, put them in a heated brooder and raise them yourself.
