Contact pop57, he can usually do very large orders. The most I have gotten from him was 120 eggs, but they were sent very quickly, and had a decent hatch for shipped eggs. On the first batch I got from him, there were 21 eggs that survived the post office, and I had 17 babies hatch. 2nd time, 120 eggs sent, 111 survived, 60+ chicks hatched. My humidity sky-rocketed during the hatch, otherwise I probably would have had more. 3rd time, 48 eggs sent, 43 survived, so far I have 21 babies, and they are still hatching. This last batch was stuck in the mail for a full week, so a 50%_ hatch would be very good!
Mrs AK and AK-button-mama can do large orders as well I believe.
I haven't gotten eggs from either of them yet. I get mine from pop cause he is on the other side of my state
ETA: Not sure if either of the AK's have A&M, I know pop does, half of my babies are A&M
