Those should be fine.I've noticed a couple of people here recommend "aged" wood chips for the run. We live in the woods and have lots of branches that fall over the winter. We chip them up in the spring and use the wood mulch to cover paths and such. Works great so far. I was planning to use these wood chips in the run and coop as well.
My question is: If the branches have been down awhile and I chip them up, is that considered aged? Or do I have to chip them and then wait a bit before adding them to the coop? The latter would require storing them somewhere, either in a container or a pile. Given our climate, I suspect that would cause them to mold and mildew so I was hoping I could put the chips right into the run, where raking and chicken scratching would turn them regularly.
Chips would be maple, alder and pine. I know not to use cedar chips with animals. I prefer this to buying wood chips, because 1) they are free and need to go somewhere and 2) I know for a fact that they aren't treated or contaminated with anything.
It's when the trees are cut live and chipped right away that the biggest risk of toxic mold blooms exist, especially in the summer when all the leaves are included.
