Tomato seedlings

Good Morning

My tomatoes (Costoluto, Ruby, Amish Paste) have all germinated now (under a bit of heat - 5days). The seed head is sticking to the top of the leaves. Is this normal? Can they be removed without damaging the leaves or should i just leave them do their thing in breaking free?

Thanks

Thank you for your reply. I'll leave them to it then as they're only attached to the seed leaves. I'm not intending to plant yet, they've just germinated. I have them under grow lights and will move to a cold frame when they achieve adequate growth.

Even here, it's cold! (although not as cold as UK, of course!) February yet to come and it usually brings winter to the fore.

Thanks again
