I have delawares and so far they have been good and their reputation is pretty good for egg production. I am working through the integration of 2 buff orps with them. All mine are pullets and not at POL yet. THe buffs are about a month younger than the Dels and getting picked on a bit. Nothing serious yet no injuries just a few blusters and and an occasional peck they can usually escape and I can separate them. They have only been together in the run for a few days and still working out who is boss.
