Not that mix. I have both those breeds, but just females and different colors than yours.
These are mixes with similar traits though. First one is a bantam cochinXstandard Amerucana. He got partially feathered feet from the Cochin and muffs from the Amerucana.
The others are his offspring bred...
Standards can hatch bantam eggs no problem. If you want lighter breeds that go broody, I suggest standard phoenixes (usually less than 4 pounds) or bantam cochins
Most of my current roos are over 5 (man I gotta start planning replacements :/ )) and still get the job done consistantly.
Some people say not to use pullet eggs since they will result in smaller chicks. But as soon as they start laying you can start hatching
