Urgent help needed with duckling incubation!

[Crazyducklady2010]

So I posted a few days ago about this same problem and I figured I'd ask again since I got no replies and I'm kind of freaking out. I had a Call Duck sitting on some eggs. She decided she doesn't want to sit on them anymore and I now have them in an incubator. I candled both of them (there is only two that are actually fertile) and they are developing nicely, but my problem is that the one egg is about 10 days old, but the other is about 19 days old! I just don't know how to handle the situation when it comes time for the older duckling to go into lockdown. I'd get another incubator, but im a small breeder and I don't have the extra money to go and get another incubator. What do I do!? Please help me!
