Should I return it to the store?

don't use it for chickens, being around cedar wood doesn't seem to bother chickens, though I wouldn't put chickens in a cedar closet either! ...it seems to be the cedar dust from shavings that irritates their respiratory system and causes serious problems for them. Definitely would NOT use it for them. If you haven't opened it, take it back.

 

I would return it. It is not the dust but rather the phenols in cedar that are bad for chickens (and not so great for other small animals, or people for that matter). It will irritate their lungs and causes liver damage. Drying the wood does not remove or reduce the phenols. Animals with a larger respiratory system are better able to handle it, but given long enough exposure under the right circumstances it will cause damage to their lungs and liver as well. An outdoor run wouldn't be nearly as bad as if you were using it in a coop or brooder, but given that there is a lot of proof of the damaging effects of cedar on small animal systems I wouldn't risk it. Personally I can't even stand to be near it when a bag is opened as it irritates MY respiratory system! And I don't have to be exposed to it 24/7.

 

I wouldn't worry about it since it's in an open run, but then I also wouldn't be putting wood shavings of any type in the run since they will only hold in moisture

 

I would return it.
Have you considered sand for your run?

 

Take it back and get a few bales of HAY, not straw, HAY. Your chickens will have a blast scratching through the hay and eating all the seeds/weeds/etc. I use the cheapest hay I can find as it's the weediest/seediest. If you garden, change this out every month or so and use it for mulch in your garden or around trees or in compost it. As long as you don't wait for their to be as much poo as the hay, you can use this directly on your garden with no problems- I've been doing it for years.

 

A friend of ours with 20 plus years of experience with poultry uses a handful or two of cedar shavings in his nestboxes under the pine shavings to deter mites. Other than that, I wouldn't use them for chickens.

 

What you use in your run depends HUGELY on where you live and the weather you have to contend with. Here in the Pacific NW there's maybe 2 months a year we could get away with using hay, every other month the moisture would rot it really fast. I don't even use it inside the coop since wet chickens bring in a lot of water in the wet months. Good straw lasts a heck of a lot long and allows the water to pass through and drain away. Wood shavings outside are also not reall affective. I use lots of sand and the occasional application to f pea gravel when I have the energy to haul it back to the chicken area.

 

I use pine shavings & cedar. I throw in a few scoops of cedar when I change my shavings and mix it all in. Keeps the smell and bugs down.
