It looks like the seed husk is still on your seedlings. If it is and it doesn’t come off soon you will want to very carefully take it off. Some will spritz the seed husk and some use spit. I have spritzed in the past and used two toothpicks to open the husk ever so gently.
If the husk is off never mind. I love your pastured we have over a foot of snow right now And it is hovering around 20 degrees f.
