I hate tracking waiting lists and getting prepaid orders, but it may be better than what I did this year. I had several people that expressed interest in chicks, then when I could see I was going to have a good hatch, I contacted them about payment and ---- nothing.
I had to keep that group and raise them because I can only ship them in a brief window. I stopped setting eggs then and THEN the people contact me later asking for chicks.
I can't force them to lay fertile eggs on a schedule and need people to either prepay in advance and accept shipment anytime, or be able to give me a decision when I contact them.
It seems like April and May are good times to hatch and ship. Probably later for people in cold states and April for Florida and Texas.
I don't really like to accept payments much in advance, in case I have issues beyond my control. With modern payment systems like Venmo and PayPal, purchases can happen very close to hatch time, which I prefer because I don't feel like I "owe" chicks to people I might not be able to supply.
I eat most of the eggs the GHF lay, simply because the demand is not there. I will certainly work with you about dates, but of course I need advance notice to collect and incubate unless you happen to contact me when I have a batch incubating already.
