AnyOne Use This Incubator & Egg Question

[DirtyDuck]

I was cleaning out my Leo Cage Today and when I started to Dump the Humidity Chamber/Lay Box I noticed some eggs 5 total 1 was alll brown and sunken in, 2 of them rolled so I didn't get a chance to mark the Top, But the last 2 I found in oroginal position. One of my questions is there no hope for the 2 eggs that rolled, and should I even try to incubate them?

My last question is I went to the local Farming stor looking for a Hovabator but they Had was " Little Giant Still Air Incubator" Model # 9200. AnyOne use his one, I think they also had a Incubator with Forced Fan model # 10200
