Is formaldehyde offgassing from plywood or OSB an issue in a chicken coop?

Friday, October 9th, 2009

I got this question from a coop builder a few months ago:

“A friend saw that I had bought OSB [oriented strand board] and mentioned that this was a potential hazard due to formaldehyde emissions. What are your thoughts on this? Am I better off returning it and going with plywood?”

Some background first. Formaldehyde is used in the resins (glues) of some manufactured wood products like plywood and particle board. The emissions the builder was concerned about are often referred to as “offgassing” or “outgassing,” which is the gradual release or evaporation of chemicals from a building material. If these vapors build up in an enclosed space, like a car or home, it could lead to a problem. But what about in a chicken coop?

What’s the best kind of chicken wire and fencing?

Tuesday, September 29th, 2009

Fencing of some kind is essential around your coop and/or chicken yard to keep your chickens in and to keep pests and predators out. Pests (mice, rats, snakes, etc.) want your chickens’ dinner. Predators (dogs, raccoons, foxes, hawks, etc.) want your chickens for dinner. There are a several kinds of wire and fencing, and I’ll talk about a handful of them here:

Galvanized hardware cloth. This is the best material for enclosing a chicken coop or enclosed run. In particular, you want 1/2″ galvanized hardware cloth (usually 19 gauge). Smaller openings could be too brittle, and larger openings will not deter against rats or snakes. Hardware cloth comes in 3-, 4-, 5-, and 6-foot rolls—with 3′ and 4′ being the most common—and in roll lengths anywhere from 5, 25, 50 to 100 feet. The mesh is made by weaving or welding steel wires together, then hot-dipping it in zinc (galvanizing it) to protect it from rust. It’s a stiff product, but you can bend it by hand, cut it fairly easily with a pair of wire snips, and attach it to your frame or posts with 3/4″ galvanized poultry fencing staples (Avoid using staples from a staple gun. They can rust easily, and if/when they slip out, they will get pecked at.) Once bent into shape, hardware cloth holds its shape well.

Chicken wire. Maybe because of its name, this is what most people think to use first on their coops. It’s made of thin wire woven together to create hexagonal openings. It’s relatively cheap but rusts quickly. And while it will keep your chickens in, it won’t keep the raccoons out. . . . (more…)
