Poultry Talk Ontario (pto.ca)

I have two broody hens sharing 3 eggs between them (one day one has them all, the next the other does)
They seem to amicably share the nesting box and eggs.
Do I let them co-hatch the babies? Or do I kick one mama out and let the other hatch all 3?
Does anyone have experience with this?

My turkeys do this all the time but I've no idea about chickens.

Depends on the hens , some get along great co-brooding others do not and the chicks end up getting trampled over the ensuing fights.

When I have two broody at the same time, I set one, then wait close to a week before setting the other. When they both hatch at the same time, there is mixups and fights and nobody seems to prosper.

I have had 2 of my broody silkies co-parent 2 sets of chicks. I had them inside the house in a large cage. Once the chicks started moving around they were fine with the lot of them. The chicks woukd just go to one or the other hen.
