I have 4 hens that have gone broody and are sitting of eggs. But they keep swapping nests, and also sometime 2 will be on one nest, and the eggs are left uncovered in another one. They can't seen to decide which nest belongs to them! What can I do? Its been nearly one week now. Usually I only get one or 2 hens go broody at a time and this has not happened before. Also after a week of incubation, if some eggs get cool as the hen has been off them a hour or so, will they still hatch? I don't understand about if the developing chicks will die if the eggs is not kept are the high temperature, or can they have periods of cooling off , then re heating? The outside weather temperature is very hot (I live in Thailand), so they are not actually getting 'chilled', but they sometimes feel air temperature, rather than hot when I touch them (when I am putting the hen back of her nest). Thanks .
