Should I take dud eggs out?

[Eggz]

I have a small incubator which fits 8 eggs (turned long-ways ) and 6/8 eggs are due to hatch in 2 days, so excited- this is my first time! The 2 'dud' eggs (one unfertile+ one with red blood ring, also no growth) are still in the incubator. Should I take them out or leave them as place holders?

Also any other tips for a first timer Thanks

At this point the viable eggs should be in lockdown and the duds should be removed. Happy hatching
