The root will come out first. Then the stem. The plant will be confused, because it will not be allowed to send the root and stem the direction they should grow, because the bag will not allow the root to go down, and the stem to go up.

I wait until I have a root and a stem with leaves (cotyledons) that are starting to turn green, then I plug them into a tray of starter mix. I find if I put them into starter mix too early, when only the root is evident, usually cotyledons do not shed the seed shell (helmet heads).

Then you have to keep it wet (I use saliva) and hope it comes free before it dies, or do micro-surgery to save it. Fingernail clippers is the best tool I have found to try to remove the "helmet". If you can get it wet enough, a knife blade may be successful in prying the shell off.

My seedlings go under lights, because I start them early enough that it still freezes every night. When I run out of space indoors under lights, they go to a heated greenhouse.

If your nights are reliably warm enough, I see no reason you could not grow them completely outside. 50F may be too cold, but 59F may be warm enough. But, if it gets too cold, your effort was wasted. I have no idea how reliable your temperature forecasts are.

Sun? Shade? If they sprout in the sun, leave them in the sun. If they sprout indoors, see "hardening off".

Thanks for your experience and suggestions. I finally planted almost all my sprouts in the vegetable bed and we will see how it goes. Most of them just had the root with no leaves, I hope I don't have the seed shell problem you mentioned, but will watch for it, in case I need to bring out the nail clippers. Thanks again!
