Looking for information and details.

Both @Molpet and @Egghead_Jr have views on this, some of which contained in this thread from 2018. The search engine here is unusually powerful.

I have no experience with it myself, my attempts at putting a Cornish over a D Brahma (don't ask) weren't successful - low fertility rates from my CornishX roo (in addition to having to wait seemingly forever for him to hit sexual maturity) caused me to abandon efforts to put the Cornish over a large, slow growing bird. I'm now selectively culling faster growth mixes, involving (among others) a CornishX hen, and yes, my Dark Brahma - not ready to give up on them yet, but so far, its disappointing.
