I would leave the pressure treated lumber as-is. No paint. Painting will actually hasten rot with pressure treated lumber. It likes to breathe. Staining is fine.
The wood is wet because after the wood is sawn and planed, the wood is then either soaked, or soaked and injected (ground contact lumber) with preservative. Wet pressure treated lumber is very normal, and is to be expected. It is normal, very normal. Nothing to get upset with at the Home Depot guys about.
Either paint your coop prior to placing on the legs, or tape the legs and paint the coop in place. If you still want to paint the legs, by all means do, but wait a while
