Hello! If your reading this then awesome! Over the past weeks I've been working on this. I have a Copper Maran and Polish rooster and ISA browns and yes they breed often. I decided to try and hatch some out to add to the flock. One hen that is CM and Polish like the rooster sat on eggs for a while and they started hatching. We ended up getting 4 in total that were completely hatched and healthy. I'm not sure what sex they will be, considering ISA browns are sex-linked and CM are not. Here are some pictures of Jerry (the rooster) and the hens as well as the 4 chicks. Now with that being said, we did experience some loss. 3 of the eggs started hatching but didnt make it out of the egg alive. I could have been my fault because I let it happen naturally under the foster broody hen and humidity levels changed throughout the day and night, but I'm not sure. Anyways if you are reading this and want to breed them, so far so good about 6 weeks into it. Although expect possible defects considering the ISA brown is kind of a mutt LOL!

I have 3 hems of that cross and they are a splash color almost white with a few bbn lack spots

How is their production? Egg color? I have a black copper maran rooster I am very fond of, I was thinking of hatching a few of their eggs.
