I hear what Greyfields is saying, and I do currently have meat birds, but I also plan on raising dual purpose birds.
I have a RIR rooster, and 10 barred rock pullet chicks. I plan on trying to produce black sexlinks with these. The cockerels we will eat, and the pullets we will try to sell. The cockerels and pullets are pleasant to look at.
My BRs are only a week old, so I can't try this out for quite some time yet, but that is the plan. If this doesn't work out well, (and cost to feed the birds is not an issue for me), I can always do meat birds again. It is not that hard. I only find that the meat birds are a freak of nature, and they look like mutants from planet X. They grow freakishly fast, which I guess is a good thing, but...
We are a hunting family, and the size and shape of the bird is not really an issue for me. I guess it will all boil down to the taste of the sexlinks.
