Problems incubating duck eggs. Help

I lost two more eggs today. This is so frustrating. This ones air sack was full of moldView attachment 1392935

I’m wondering if the sponge should be removed.. that can hold tons of bacteria in itself. Just use bowl of water.?

And without air movement.. mold city.. they breathe it in through there pores.. so that’s my guess..

Thanks for your input. The sponge was brand new. But I did remove. Its hatch day now. I have three eggs left. And 2 are internally piped
