I tried to explain this to a guy, yesterday. He called me on the phone and asked me lots of questions, talked for a long time. He lives in LA (the state). Not sure why he chose to call me, out of all the people on BYC. He wants to raise productive chickens. He bought the Frying Pan Special from a hatchery, but wants to choose one breed to raise. He's been reading some of the popular threads like the Fermenting Feed, etc. and is totally confused about the conflicting information and very high prices on chicks. He couldn't tell who to believe, from reading all the info on BYC.
I recommended that he try an easy breed like White Rocks or NH and post questions on the Exhibition thread to find a good breeder.
