I am ordering 5 pullets of each of the following: Australorps, EE's, Dominiques, Buff Orps, Salmon Faverolles. They will be housed together in a common pen. Egg production and 'fun' only. I would like to have one rooster (maybe 2?). What would be the best breed to choose to have a rooster in? And are these breeds compatible? Do I need 2 roosters for a 25 hen flock or just one? If two should they be the same breed? The same size? Thanks for the input.
