Going broody toogether

[Japetus]

Two of my pullets decided to go broody at the same nest at the same time. I have put both of them together -on different nests- at a quiet place at a cellar but I haven't yet placed eggs under them, just one on each to keep them broody.
Should I place eggs on both of them the same day so that the chicks can hatch at the same time or can there be a 1-2 days difference?
I already have a bunch of eggs I can place now but I am expecting more to come from a friend in two days time.

You can give eggs to the hens at the same time or have a few days between them; your choice. Should they hatch together or close they might coparent and raise their chicks together.
