I've just hatched my first SLW in my new incubator. It's been a long night cos he hatched from wrong end. But with bit of help he is now out. He still has bit of yolk attached and he's trying to move around and stand up. Will that told dry up and fall off or do I need to help remove it?? He's moving around banging in to other eggs starting to hatch. Is this ok?? Thanks in advance.
