Can I save them?

I have 50 seedlings planted in a tray or a flat (to start seeds) sitting outside on a big ass rock in the woods and I think something has been eating them. About 37 have sprouted, but only 24 have tops one them, and the rest are just stems. They've only been growing for 6 days and I'm probably gonna plant 50 more so I'm not that worried about. So should I just pick those stems out or can they still survive.

Also, I've been visiting and watering them every day, and I know a couple that didn't have leaves today had them yesterday.:mad:

Well all but two of them were eaten. I'm pretty sure it was rats, because there was some cardboard that was torn up around the spot. I planted 50 more and I'm gonna plant 50 more later. I have these sitting inside so nothing can eat them this time.

what a piss off

I know. I was so mad, it ruined my day. Oh well, at least those weren't my really good seeds, then I would have fuckin' been killing people. lol
