I'm curious if anyone else has had experience in the area of having eggs split between a broody hen and the incubator. They both hatched within a couple of days of each other, the broody a day or two before. What is odd is that the incubator / bathtub chicks are larger, have more feathers, are more mature.... just seem "older" than the ones walking around with their mother. Odd or normal? (three weeks old now) Thank you.
