CO is 28 and air is roughly 29 (mixture of O2 which is 32 and N2 which is 28).
So CO is slightly lighter than air.

Before you buy: Illinois Smoke Alarm Law- Effective January 1, 2023
The updated law requires Illinois residents to replace their old smoke alarms with the type that has a long-term,
"10-year sealed battery." This would apply to residents that are still using alarms with removable batteries or alarms that are not hardwire.

You were talking about heavier gas concentrating in lower layer which I didn't say that.
The air does not split in layers because O2 and N2 are already thoroughly mixed together. If you simply release new O2 in room, guess what, it will initially lay on floor.
And come to the case of CO. It will be newly released into air by combustion so it will initially be floating high on ceiling because:
1. it's lighter
2. it comes from combustion with higher temperature.
Sure eventually it will be mixed with air and everywhere but that doesn't matter any more.
