I want to get started selling eating eggs and hatching eggs. I was wondering which kind of chickens would be best for that. I guesse some kind of sex-link, but my rir lay an egg almost every day, would that be an ok choice. They would have 1-2 10x10 pvc coops. How many laying breeds could I fit in one? The coop would be moved once a day. One last question. Since sex-links ain't pure breed, would chicks from them be pure sex-link? Thanks!!!
