Chicken coop maintenance: Plastic coops

It's that time of year again.....yearly coop cleaning! Oh sure coops get cleaned weekly, some stuff even gets done daily but the big cleaning is a once a year deal. This time we're going to discuss the maintenance needed for plastic chicken coops. 

There are all kinds of plastic coops people use. Our Silkie coop is a converted child's playhouse that we found on Craigslist, though I did consider using one of those large plastic garden sheds. Many people use the small 'garage style' sheds that can be bought at home improvement stores and warehouse clubs. 

Still others have converted other outdoor structures into coops. Whatever the case may be your chicken coop is going to need a thorough outside and inside cleaning at least once a year. Enter the power washer.

Plastic chicken coop cleaning

Power washing is like hand scrubbing, only without the elbow grease. In fact, it might even work better! It will easily get into all the nooks and crannies and decorative details of your coop, blasting out dirt and those nasty green moss particles that grow on the roof. 

Power washers come in all shapes and sizes, but lets assume you're going to use a typical home power washer (not one of those industrial'll blow holes right in your coop!) You're going to want to start with a warm dry day. It'll take forever to dry out if it's a rainy day and then you'll be putting the chickens back into a wet coop at night...bad idea.

First step is to remove everything from inside the coop, and I mean everything! Take the roosts out if you can. Remove the nest boxes, feed tubs, even hanging feeders if you have them. Clean out the bedding and sweep the floor. If you have electric you'll want to remove as much as you can and cover everything else with plastic bags secured by duct tape. UNPLUG YOUR COOP! Flip the breaker if you have to. 

Whatever you do don't spray it with water if the electric is still on! I cannot stress that enough.....(quit know somebody, somewhere did it!) 

While everything is outside this is the perfect time to scrub nest boxes. These I scrub by hand because I like to clean them with dish soap and Oxine. You can use bleach if you need to, but make sure to rinse thoroughly. This is particularly easy if you used my Free Nest Box idea. Set them in the sun to dry and start on the outside of the coop.

Most plastic structures aren't airtight. So what happens is, when you're spraying from the outside water is gushing inwards through the cracks and when you're spraying inside it's going outwards. The dirt moves with it, which makes for just a tad bit more work. 

Start at the top and work down. Always work down! Poop is at the bottom and you don't want to push this up. Roof first, then work each side top to bottom. Don't hold the sprayer on one spot for very long, you don't want to damage the plastic. Several passes back and forth are better then holding it in the same spot.

Do the porch, floor or base last. We have a wood base and it gets slightly green from algae or moss or whatever it is that grows in this shady location. That gets blasted off too. Once the outside is 'done' move inside and take a minute to look around. 

See where water came in through cracks and crevices? Those are your winter draft holes. Make a mental note on which ones you want to plug up (chicken level) and which ones you want to leave open (ceiling level). The loose rule on this is, if the draft is on the chicken, then it's a draft and if it's above roost level then it's ventilation. 

You can work on these later now that you know where they are. Now you can start your power washer back up and get spraying. Ceiling first, then each side working top to bottom once again. Be careful around any electric even though you taped it off. It's better to have to scrub a few spots by hand then to ruin anything. Finish with the floor and your ready to start outside again! Oh wait...did you think you were done? lol

how to powerwash coop

You can actually just switch to your regular hose for this part. Remember how water and dirt blasted into the chicken coop? Well, it blasted back out in the same spots and your clean outside now looks dirty again. This will hose right off though. A quick spray and you can call it done! You might want to squeegee the floor inside if you don't have good drainage, but a few hours in the summer heat should dry the coop right out.

Once it's dry add fresh bedding and put everything back in. Wasn't that easy?

  1. Looks nice, but I will say I prefer my deep litter method. Four times a year, throw all the nice compostable pine shavings into the veggie garden, replace, all done!

    1. Well, it actually doesn't matter what litter method or type you use....I was trying to explain how to do a yearly cleaning of the walls, ceiling, roof etc. No matter how you handle the litter: poop, dust, dirt and cobwebs need removed from the rest of the coop on a regular basis.
