I set some French Black Copper Marans eggs under a broody hen 3 weeks ago (Friday 6/10). Saturday morning I found one perfect, fluffy little chickie under mama hen. This morning, mama is off the nest showing lone baby around the dog crate/nest box. There are 3 eggs left in the nest. How long do I wait before disposing of the remainder of eggs? Or has the broody hen already made that decision? I should mention that they are ebay eggs and were in transit for 5 days (I frankly didn't expect any to hatch).
