Mypetchicken.com, awesome sauce IMO!!!!
Started out with them for chooks, ordered two separate batches, they were always ready to answer my (many) newbie questions, chicks were great, sexed 100% correctly both times, awesome customer service...I'm in NJ, they drop shipped from Meyer. Difference between MPC and Meyer chicks, Meyer I believe has a large minimum, also they don't sex bantams. You can only purchase straight run day old chicks from Meyer. MPC has a chicken sexer that sexes those Meyer (and other hatchery) bantams.
That is a skill and worth it for the extra money not to have extra roosters (I am not fond of the idea of extra roos as warm packing peanuts, ugh).
I have enough roos (from hatching my own, lol, not MPC) so if I ever order more it would be from MPC or a local breeder who sexes their birds, or I'd buy started pullets.
Another thing with MPC, like I said they have great CS. On my initial batch, one tiny d'Uccle didn't make it. They gave me so much good advice to try to help that baby pull through (I mean I was a brand-spanking-newbie at that point). They were kind and respectful when she died. They reimbursed my money with no question.
I feel I have the perfect flock now, almost two years out, no regrets. I have ordered non-chicken stuff from them too (just bought a Cozy Coop heater that I have yet to hook up) and would not hesitate to get babies from them again...when mine start dying off I will definitely get some more d'Uccle pullets cuz that breed has my heart.
Good luck!
