If you want eggs buy the best layers. Isa Browns will beat anyother bird hands down. If you want meat go with cornishX. I do both and got 310 eggs per hen last year. with a cost of close to 50 cents a doz. My meat birds I grow big but have about $.80 a lb. in feed cost in them .I dress them at about 10lbs. I make my own chicken mash for all of them whick cuts cost. I do feed alot of whole corn to the meat birds. Have had only one lost bird this past year. Limit the feed is the trick with meaties. Corn is selling for $6.15 a bu. today(56lbs). Soymeal is about 20 Cents a lb now. My cost will be higer this year. I buy from a farmer. One of the best places to get chicks is www.townlinehatchery.com
