I wouldn't you never really know what you are truly getting and hatch rates on shipped eggs are not to good also many times the eggs cost more than local ones.
How long have you been looking for peas? it took me 7 months to find a breeder near me , run an addy on your local classifide site...
This chart is for duck eggs but the development stage is pretty close, most of mine hatch by day 25 weather they are under a hen or in an incubator but others here have their hatch on day 28 .
If you read threw this thread there is lots of good info on hatching peas and methods folks use, for instance the post 2 above this one has info , guess you missed it.
Contact Frenchblackcopper in the post above he most likely has what you seek
