Dehumidification question

[EggWalrus]

Those EvaDry are not meant to be used outside. They are for small closets and maybe a room the size of a bathroom. All EvaDry is, is a overpriced plastic container with a silica gel desiccant in it. The one that plugs in to "Renew" itself, it has a small heating element in it also. You can do the same thing with bulk silica gel in a coffee can with holes or slots. Then once every few weeks, dump the wet gel on a pizza pan with some parchment paper. Put in oven for 2 hours at 250°, and "Viola!", your gel is like new again. You can get a whole gal of gel crystals for the price of getting less than an EvaDry. That EvaDry barely has a cup of gel in it.
Basically you get 16x the moisture absorption for the same price as EvaDry.
Here's a link.

PS No gel moisture absorber is meant to be used in an outdoor environment that has ventilation like chickens require. The air exchange rate should be too great for any absorber to make a difference, and you would have to "bake"/dry out the crystals every couple of days .

@aart, Thanks. Just trying to learn this stuff in my first winter with laying hens.

...or hours.

has anyone ever tried Eva Dry dehumidifiers ? I have added vents in my coop and still have too high of humidity. I added some extra wood chips in the covered run yesterday and they are not helping as they are wet. I googled lowering humidity within a chicken coop and found a place suggesting these dehumidifiers.re safe and quiet and require no power or batteries. Apparently they work for a month or two and then you renew them by plugging them in. Seems way too easy

May I ask, where did you buy the HDPE for your coop floor?

I searched a local place ( Toronto ) that sold plastic sheets goods. They delivered right to my door. It was super easy to cut and work with and so easy to clean. I am sure there is a place near you depending on where that is.

Hi everyone, I need some help. Soon will start the rain period and I have a problem during this time with the humidity in my coop. I have made an additional window there and it didn't solve the problem. I noticed that during this period my birds don't feel good and the number of eggs per day is small. I guess that this is because of the humid air, don't you?! That is why I'm thinking about buying a dehumidifier. I even found this site dehumidifiercritic.com it is a guide that helps to find the best dehumidifier. Do you think this will help?!

You can't make the coop less humid than it is outside.
Using a dehumidifer in a coop won't work as you can't dehumidify the whole world.

Measure the humidity inside and outside the coop...they should be within ~10%.
If inside humidity is higher than outside, then more ventilation is needed.


Not sure about the 1sqft per bird, not always possible and can depend on air flow due to where openings are located.
This is think link I usually suggest, a pretty good discussion about...

Hard to know why your birds "don't feel good" and not laying well.
Could be many reasons....
....but if it's humid and hot, that doesn't feel good to them(or me-haha!).

If you want some help with your coop ventilation,
post a new thread here with pics of your coop, inside and out.

If you want some help with laying,
post a new thread here, with info on your flock(ages, etc) and feed.

Welcome to BYC! @turelan
Where in this world are you located?
Climate, and time of year, is almost always a factor.
Please add your general geographical location to your profile.
It's easy to do, and then it's always there!

Welcome!
Adding your location would help, but having a rainy season sounds tropical or sub-tropical to me. If it's very warm where you live, having a very open coop helps the most. The goal isn't to have lower humidity than ambient, but to have good air flow and ventilation, and protection overhead from rain.

And shade, protection from the hot sun. Cold water to drink often, if possible, cold or frozen fruit as treats, ice in the water too.
And selecting breeds that do best in your climate.
