Y aren't they developing?

[taraann81]

Hi everyone. My Muscovy laid around 25 eggs. I took 8 eggs and put them in the incubator 11 days ago, I candled them and I can see good veins. Today I went and checked the eggs I didn't take, she started setting on them the same day as I put the ones I took in the incubator, so she has also been setting on them for 11 days. None of hers seem to be developing. I wonder why this would happen? Odds are(I would assume)if all the ones I took from her were fertile the majority of the ones I left with her should be too.
She has made her nest on cement and it is chilly here still, could that be the reason? Even though she is setting perhaps the eggs are to cold? Any ideas?
Thank you

Nobody can help me with this? I'm not sure if I should continue to let her lay on them or discard them,

I'm not sure of the answer, but you should cross post this in the incubating and hatching section. I know you will get responses there!

Thanks, I tried but also had no responses. Oh well, I guess I will just wait and see. Thanks again
