@cgmccary That is exactly why I am looking for Buckeyes. But now, I'm a little concerned being told they require the 30% protein starter b/c that doesn't feel like what they would have been getting on a homestead back when, & my goal is to get my homestead animals away from feed store feeds as I am able to produce our own feeds here on farm (not there yet, but aiming towards it). BTW- I had exactly this issue w/ rabbits, all the production/modern meat breeds require such specialized high protein feed that it didn't work out for us to raise them, just not functional on a small scale. I get the economy of scale, grow fast protein conversion plan for big commercial producers, but that is just opposite of the needs of someone aiming for self-sufficient homestead food production.
So in the opinion of those more knowledgeable than I, would any of the Lg breed in need of preservation dual purpose breeds be better (than Buckeye) for a real old fashioned homestead situation like I have here. I had settled on Buckeye but I am open to being told there is a better choice for me. I'm ready to take the step to a rare old breed to help keep the gene pool going but it helps nobody if I pick a bad match for me.
(I'm in the mtns & have had temps on rare occasions to -20F in winter, but also sometimes to 80F in Dec & Jan, snow to 12 inches as late as April, Summer droughts 5-8 wks long, temps over 100 for up to 3 wks running.) I need a cold & heat hardy bird that will give me above avg. egg production, and culls dress out to something better than a game hen size, something w/ real meat on it. It is a lot to ask of one breed I know, but they do not need to be fast maturing (I can give up some time in trade for their ability to self feed to some extent on free range). I feel like my situation is very much like the folks 100-200 yrs ago so surely their breeds are where I need to seek for a bird that can fill that need. I'm very interested in the opinions on best breed for me from those on this wonderful thread, most of you clearly know far more than I do about these breeds....
All input welcome

Thanks

Well, it's your decision. I understand why you want to do it right the first time. I am reading a non-fiction narrative book about a lady who homesteaded in Burnt Cabin, Wyoming circa 1889. She particularly mentions her Plymouth Rocks and all the excellent eggs they give her. I know there are some very vintage lines of them out there. Buckeye is a good breed.
Best,
Karen
