I finally set eggs again last night. 19 possible OE. From my Marans roo x EE/Leghorn mix. They have pea combs so I'm hoping the chicks have the olive egg (blue) gene. I added a fan to my bator so we will have to see how that goes. Can't wait for my Brinsea Spot Check to get here.
ETA: Since the mama is half leghorn the chicks could get the white egg gene right? All the eggs in the bator are light blue.
