I opened up my shed this morning and noticed that 1 roof panel of the chipboard roof looked wet, the shed is only about 6 months old and the felt is fine (not damaged).


I assume that the roof is being affected by condensation/humidity from the hens at night due to them being in doors longer.


I am going to improve ventilation to try and remove the humidity in the shed, but can anyone suggest anything I can use to spray on the existing mould that is safe for use with poultry?


I have wiped it off but am sure to will return until the humidity is improved.

Tha humidity is a bigger problem to the chickens than mould as it can result in respiratory problems.

HG do a mould spray for use in showers which would be ok I think, if you did it first thing in the morning and left the front off or whatever til bedtime.

Improve the ventilation by cutting squares out under the eaves and covering them in weldmesh (to keep out stoats etc.

You can use the vents from B&Q or where ever that you would use for your house if you get and adjustable one you can alter the draft. Just cut a hole and screw it together.
Also put it higher up away from perches as chickens will avoid drafts

Thanks for your posts, I had already fitted 2 "house style" vents which incorporated a fine grill within the vent. I removed these grilles today as they were blocked with dust.


I have 1 vent at ground level and 1 at the top of a side panel (below the start of the roof panel, tomorrow I am getting another 2 grilles to fit closer to the apex of the roof to help remove the hot air in the apex.

We scrubbed the mould with neat Poultry Shield. In summer we painted the plywood affected with primer and one-coat gloss. Problem is plywood and chipboard doesn't 'breath' due to the internal non-porous adhesives. We use proper wood boarding wherever possible. As said the root cause is inadequate ventilation.

As said the root cause is inadequate ventilation.

Or maybe simply permanent high humidity. Why should poultry be better off than humans... I can't get my house mould free, much as I keep ventilating, washing with bleach etc...

Well after removing the fly grills on the vents yesterday the roof panel seem to be drier today, I have also added a 3rd vent just below the height of the apex. Strange that only 1 roof panel is being affected, then again the non affected side is in a bright sunny location (when it's not raining  ).


I'm hoping this will now remove the rest of the moisture built up during the night.
