My broody Silkie is sitting on coturnix eggs right now. She has successfully hatched clutches of chicken eggs several times. I expect her to be successful hatching quail too!
My D'uccle hen is also sitting on quail eggs, but she hasn't been great at keeping them under her so I'll be surprised if any hatch. This the first time she has went broody.
Update on my Silkie brooding quail eggs in about 2 weeks!
Oh you just have to let me know how they turn out! I want to do it so badly!!!
