I would say it would be a question of taste . For eggs , I would definitely say chicken . For meat , if it was me , I would have to say turkey because it is my favorite . When I still lived on our farm we had all three , chickens , ducks and turkeys . Oh , and we had guineas .
Do you live in the country or within city limits ? That would come into play as to what kind of birds you wanted to keep . It is against city ordinance to keep chicken , turkey or duck/geese in my town within city limits . We are allowed to raise pheasant and quail though as long as it is on a small scale , in other words just two or three each .
