Every time I incubate I seem to have a lot of dripping/stinking eggs?

Every time I incubate I seem to have a lot of dripping eggs or eggs that go bad.
I use the brinsea eco and I use my own backyard eggs. Out of 9 to 10 eggs I usually have 3 or 4 hatching,
around 3 stinkers/drippers and a couple that never hatch. Is this my chickens or is my incubator dirty (bacteria)?
This happened 4 times in a row now. Just wondering what could be the cause.

Humidity too high, maybe? I had the humidity too high at the beginning of a hatch earlier in the summer and most of them went bad.

I scrubbed and disinfected with bleach after though too to make sure no bacteria left behind.

That could be. We already have high humidity..
Maybe I should try a dry hatch.

Do you keep your incubator clean?

Yes, I have the brinsea eco mini, I use bleach and I screw off the plate that covers the heating element that is usually covered with dust/chick fluff

I just asked because I have seen some incubators that the owner could not figure out what was wrong with it; find they have not washed it once since they got it, however many years ago...
