Have you done that before? And when you say cornish, do you mean cornish LF, or CX? Man that gets confusing. Sometimes I see why the Cornish LF guys get testy. LOL.I raised cornish for a very long time. Since iI purchased English Orpingtons I processed my last male. I have two hens left that are getting pretty old. I have not hatched from them this year and i will make sure I do in spring so I have cornish/orp for food next winter.
The gentleman in Sequim who's teaching me the lost art of the capon, has been using a 3/4 Dark LF Cornish/Buckeye male over Del hens. Seems to work very well for him! I'm hoping to find a good mix with the HRIR, either a male or female blood that works out nicer than the originals for meat. It truly seems hybrids work out the best for earlier harvest. "hybrid vigor" has it's root in something. And all our breeds started out thataway, took years for someone to get them to breed true.

Ok, back to makin' dinner.
