Wow nice to know, I'll certainly look into the black sex link, will they integrate w/ my flock easy? funny I'd been checking on egg cartons and containers last night since some of my friends here are interested on buying eggs from me.
As easy as any other breeds (technically they're hybrids and not breeds) will. All new chickens, no matter what breed, need to be integrated into an existing flock slowly and carefully. There is a good article on how to do it at http://poultrykeeper.com/general-chickens/introducing-new-chickens.
