Help! Muscovy Egg headed to compost unexpectedly hatched! No mom

[Muscovy-palooza]

Mom muscovy has been sitting for entirely too long. Her eggs keep rolling out from under her and getting cold. I did slip a couple of other abandoned eggs under her thinking possibly she could hatch them. I relocated the nest but many of the eggs were dark so I thought that it was time to release that hen from the burden of likely bad eggs. My son looked in the box that had the eggs in it since this morning (were sitting in sun) and said that one was moving. The little thing hatched right there in front of us. Now what? I dont know where mom is. What should I do? I put the little one in a box under a heat lamp. I have one 3-4 week old muscovy that we found roaming with no mom. I have 10 total that I have been brooding. Should I move older one in with new duckling? Or leave it and other potential hatching eggs under the heat lamp? I dont have an incubator. Thanks for any guidance.
I currently have the duckling and the other eggs under a heat lamp with a heating pad underneath.

@Miss Lydia is a pro at this stuff!

I wouldn’t put a new hatching in with an older duckling with out a barrier the new one need sometime to recover from hatching. Any more eggs looking like they may hatch? You can candle and also listen for peeping and internal pip.

Can anyone tell me if any of these eggs look viable?

My eyesight is bad, but those look un-fertile to me. Do you see any veins?

Yes veining in a couple of the eggs. At this point I just want to make sure that I don't have any that are ready to hatch. If they are just fertilized yet a ways from hatching I will just let them go since momma hen has moved on from the nest.
Maybe next time she lays eggs it will be in a better spot.

I think your safe In letting them go.

I made a short video of one egg that has movement inside. I believe that it is the little break moving as the little one breathes. Now what? Do I slip it under a momma that has just started sitting and keep checking if it has hatched or keep it under a heat lamp? There is definitely life inside that egg.

Okay can you put the video up?
