My white leghorn is broody. This is her second time but I stopped her the first. She was on the nest yesterday evening, but when i lifted her to see what was underneath, she bolted for the coop. Found her today sitting on two ping pong balls, so I added some EE eggs to a nest a set her on it and that's where she is staying. About 9 eggs from all different kinds on hens, all mated with a mottled houdan roo. This is my first time hatching, is there anything special I need to do? Should I separate her? And how long does it usually take to hatch? Thanks! Looking forward to my first chicks!
