I'm trying to pick some good dual-purpose farm breeds. These are the traits I'm most interested in: Must be a very-good or excellent layer. Cockerels must be large enough/plump enough to butcher (I know they won't compare to the Cornish ). Must have an average or docile temperament (I don't want aggressive, flighty, etc.). No Sex-Links (must breed true). The breeds I'm considering are: Barred Plymouth Rocks Buff Orpingtons Rhode Island Reds New Hampshire Reds White Plymouth Rocks Black Australorps Rhode Island Whites Please let me know your experiences, good and bad, with these breeds. Please help choose the best three or four breeds for me! (BTW, I'd be getting these from Ideal Hatchery) Thanks!
