Hello BackYard Chicken keepers, I have a few question about seramas and was hoping that some of you might be able to answer them: 1. How long do the eggs take to hatch? 2. Can you hatch them with bigger eggs? 3. Can they be hatched under a bigger hen (specifically a Wyandotte cross)? 4. Will the chicks be able to survive with a flock of larger birds? Thank you!
