Thanks, I may try that. I added a Tupperware with a sponge in it and have been topping it up with hot water and was able to get it over 60 finally. I checked on one that I thought had I internally pipped early and it appears to have died but I left it in just in case. It was a large pekin egg with a huge air cell. That leaves 4 more pekin and 3 blue runner eggs. Fingers crossed for healthy duck babies. This is my third hatch, first with ducks, and I haven’t had to deal with any losses this late in the process.
I hear one chirping this morning so I may get an Easter Monday hatch!
How is your hatch going Aa?
