Help! Abandoned Duck Eggs

[jane3412]

I have eggs that were abandoned. You can see feathers where mom was probably killed by a fox and one of the eggs was out of the nest but not broken. I brought then inside because our nights are still fairly cool but they were away from any direct heat for at least 6 hours. I rigged up at light and was able to get the temperature up to 90 degrees. I candles them twice. Once when I first brought them in and the air sacks are large. I candles again before I put then under the light and I could see membrane veins and again very large air sacks.

I know from reading that they need to be warmer, but is there still hope they will hatch?! I'm going to get an incubator now.

Maybe.....if you get them in a incubator really fast!

Should I be turning them once they're on there or treat it as a lock down?

 

[lightchick]

Do you know how old they are?

I think you are suppose to turn till they go into lock down.. here is a candling chart maybe this will give you an idea where they are in developing.

Do you know what breed of duck? mallard 28 days Muscovy's 35

They are far along! The air sack is pretty large and noticeable. I'm guessing between 24-28 days. I have them in an incubator now with the water channels for humidity. I put them in when it read 90 degrees in hopes it it would slowly increase the heat and not shock them. Thoughts?!?

Comparing the egg colors and size, my guess is Muscovy eggs. There is no blue tint to the eggs and they're fairly large.

My Muscovy eggs have never had a blue tint. olive tint though. I'd say bring temp up slowly is a good idea.

Here's some good info on hatching Scovy eggs

So yesterday, I caught the incubator at 112 degrees freaked out and took the lid off till the temp cooled down. It was 91 degrees after that for a few hours. Today, I've been able to keep the temp between 97-102. This incubator is driving me crazy. If I lift the lid, I'm noticing a smell. I'm not sure if the eggs are rotten or what happened. I've candled 3 and they all look the same. The air sacks are dipped to one side and large. But I'm not noticing any movement while candling. Should I be at this stage?

How do I know if the eggs are bad? How long should I wait to see if they'll hatch?
