So I have a baby that is on day 63 and now out of the egg. But he still has lots of his yolk sac left. I read on a previous thread to put them in a small plastic container or deli cup with wet paper towels until its absorbed, so that's what I did. The yolk looks very odd to me though. It doesn't have much yellow color to it and it has lots of red blotches. I've heard that you can use unflavored dental floss to tie it off, but I want to hear if that's necessary or not. This is my first baby to ever hatch and I need some help! Any advice is very appreciated..
