I have 16 pullets- BarredRock, blue laced red Wyandotte, crested cream Legbar, and a mix of CCL and white leghorn. I have two cockerels that are CCL and BLRW but I don't have them separated by breed. None of my pullets seem to want to be broody so I bought an inexpensive incubator and just had to try it out. So I took some of my eggs and put them in it and now have chicks in the brooder 7 that I hatched and 3 cuckoo marans that I bought at the co-op. I have 15 Black Java eggs in the incubator now. They are shipped eggs. I had been studying up on a really good dual purpose breed and decided to give them a try. Not too many people have them and that appealed to me too. But one thing I really like is having lots of colors in my egg basket. That's why I added those marans. Hope theirs will be dark. I'm guessing some of my brooder chicks,if girls, will lay olive eggs. We'll see. I know you will enjoy your chicks.
