Weatherproofing my coop further

[3SiameseCats]

My coop has begun to get real musty when it gets closed up at night. The coop is an old plastic shed, and while the roof does its job, water seeps in through where the walls and the floor meet on the edge. So I need to seal that up with something. Is there anything i should avoid?

It sounds like you don't have enough ventilation. Can you post some pictures?

Can you seal the area from the outside, or do you have to do it from the inside? I have sealed up cracks/seams with exterior caulk. I do it from the outside, on a nice day, hopefully with a breeeze to blow the smell away.

Can it be elevated up on a platform to get it off the ground?
Pictures will help.

I plant to seal it on the outside. And yeah, I don’t have enough ventilation. Working on giving it more.
