Pallet Wood Flooring for Chicken Coop
When I first built my elevated chicken coop, I used OSB for the floor board and covered it with linoleum I got on clearance from Menards. It lasted 5 years, so I'm not complaining. But the other day I started my semi-annual coop cleanout and noticed a number of soft spots in the flooring.
For reference, I use dry deep bedding in the coop. Typically 4-8 inches deep. It's not a true deep litter system because I do not actively encourage moist composting inside the coop. However, even with the dry deep bedding, the chicken poo works its way down to the flooring and can get a bit moist.
Over the years, the linoleum has started to crack and rip. I was expecting that, and I think 5 years for linoleum inside a coop was probably all I could expect. This new group of chickens I got last year has been really tough on the linoleum. I have seen one of them peck and rip up the linoleum on purpose. I don't have any idea why. I don't know if it was just one chicken doing all the damage, but damage was done.

As I was cleaning, it became apparent to me that I had to rip out all the old linoleum. It was in worse condition than I thought. Worse yet, the soft spots under the linoleum were rotted OSB board and some places had holes in the flooring. I'm not sure how the OSB got rotted underneath the protective cover of the linoleum, but it was really bad in some spots.

I have been thinking about methods of floor repair for a few months. I really don't know what would be best. But I decided to cover the OSB with pallet wood planks for now and see how long the wood will last - without any linoleum covering - with my dry deep bedding system.
Here are a couple of pictures of the first half of the coop floor covering the worse spots. The first picture is pallet wood covering the worse spots in the coop. The OSB underneath the nest boxes had completely rotted out, despite linoleum covering it. No pictures of the before problem, but here is the pallet wood flooring I laid down on the first half of the coop...

Here is another view of my repair job. I used 32-inch-long planks, which is about all I can get off the pallet planks once I trim the edges square. As you can see, I laid them down lengthwise in the coop which is the same direction I will be shoveling/sweeping the coop litter out when I do my semiannual coop litter cleanout. The idea with the boards in this lengthwise direction is that it would be smoother to sweep out - as compared if I had laid the boards side to side, for example.

Ascetically, you would never lay down floorboards like this inside your house. That would look just terrible. You don't want an obvious pattern like I have.

However, for a chicken coop floor, this is a better layout design, having all the boards exactly 32 inches long laid down in rows. If/when a pallet wood floorboard needs to be replaced, I just have to pull it up and plop down a new 32-inch-long board.
At worse, I might have to rip it to size because all the boards are different widths. I had considered ripping all the boards to exactly 2-1/2- or 3-inches wide, but that would mean more waste, and I wanted to make maximum use of the pallet wood planks I had.
Yes, there are some small gaps between some boards, but I can live with that. Remember, it will be covered with anywhere from 4-10 inches of dry deep litter.
Along with that, I made no effort to ensure that all pallet planks were the same thickness. Most of them are about 1/2 inch thick but could be more or less thick. It's not a level floor in that respect with some boards sitting taller than others. For my chicken coop, covered with many inches of coop litter, it will never matter.

I would love to hear feedback from anyone about what you think of my pallet wood floor for my chicken coop. Has anyone else tried this? Are there problems I have not considered? I can tell you, that right now, the floor no longer has soft spots and feels much more solid than before. Today, I'm happy with the repair.

I am hoping to get at least a few years out of the pallet wood flooring before some boards start rotting. I suspect the floorboards first to rot will probably be in the same places as the original OSB floorboard failed. But, in the meantime, I have saved money using these sacrificial pallet wood planks for the repair. After discovering the OSB rotting out underneath my linoleum, this time I think I might prefer to see the actual condition of the floorboards when I do my semiannual cleanouts. Nothing hidden from view after the coop litter is cleaned out. If a board(s) need to be replaced, I'll be able to see it after sweeping the floor.

I ran out of pallet wood floorboards to do the whole floor in the chicken coop. I had gone into this repair thinking I would only have to patch a small section of the flooring. I thought I had 3X more pallet wood floorboards ready to use than needed. But now I have decided to cover the entire floor with pallet wood. I'm not quite halfway done with the whole floor, but the worst part is fixed and covered.
Anyways, I would love to hear any thoughts from others - pro or con - on this pallet wood floor repair. Later...
