Sandy it is a bit early to chitt maincrop potatoes.
First earlies should be sown in the second half of March and covered to protect from frost at night.
Second earlies should be sown early to mid April.
Maincrop should be sown late April or May up to May 20th.
Best advice to is keep them cold and if they sprout too early you can take off the sprouts. This will put them back by up to 3 weeks.
I don't chitt maincrop at all, just plant them earlier if you want an early crop.
