I saw a minimum was 8 for BR.
Actually, Porters explains that the number in () is the max number of that type of turkey available at one hatch.
From the Porters page:
Quantities:
The number in parentheses "( )" after the price of the poults indicates the maximum number of day olds available at one hatch. You can order as few as one of a particular variety. If you want more than the maximum number, you will either need to place two orders from two different hatches. Or contact us to see if we may be able to make an exception and fill your request in one shipment
Hmm. This put me in a bit of a situation. I know others were wanting the BR as well. I may just have to order my own and get 15 poults. Thanks for pointing that out. I hadn't seen that until you said something.
