condensation on a metal shed being turned into a chicken coop

[Plattsmouthchickens]

so i am considering converting a metal shed into a chicken coop. I have been seeing many posts about condensation on the roof causing some moisture issues inside the coop.Please don't think I am ignorant but, what if you sprayed a flex steel sealant on the top of the roof? would that help? I need another coop but plastic is very pricy and wood does not last all that long. any other ideas?

Add lots of ventilation. Condensation is from the water vapor inside.

the shed already has a couple of vents that are on it from the manufacturer. it will only house 2 chicken and is more than likely going to be 5x3 or 6x4 not sure yet. would you still recommend adding a couple more vents at the top of the shed (not on the roof)
but at the top of the walls?

Definitely, the manufacturer vents aren't even close to enough.

Spraying sealant on top of the roof will not work. Like nuthatched said, the drips are from condensation of the water vapor that rises to touch the colder underside of the roof.

Some of the pro shed builders here use metal roof panels with a thin layer of insulation attached to the underside of the roof panels. It looks like it might be a film of closed cell - something noticably more than a vapor barrier. It seems to come that way; I think it is important that it be tightly attached to the roof panel. I speculate that it can't sag down or moisture would be trapped against the roof.

That method needs a coop big enough and designed so the chickens can't reach the insulation.
