I have 2 Bourbon Red hens setting on eggs. I had been thinking about buying an incubator to hatch some Black Copper Maran chicks. However, my BR's are setting so well, I decided to add some chickens eggs to see if they will hatch them for me. Has anyone ever done this? I'm curious to hear what your success rate might have been. This would be a perfect solution if it works like I think it should.
