We live in rural SC, our calls usually come in about 5:45, as soon as the delivery is made. Love the peeps, usually have to open the box and "share" the little ones. They love chicks, ducks and baby geese.
I have 8 white call ducks, some are getting pretty old. They hatched about 40 young among themselves this year. Two hens are no longer laying. I guess 8 years old is their time to retire.
