I was just standing at my back door staring out through the snow to the spot where I plan on building the coop later this spring. Something struck me, but I don't know if it's a problem or not. Somebody told me chickens are sensitive to a lot of things. I can't remember all of them. However it seems they mentioned low PH. I was wondering about this. The coop and run will be directly under a big blue spruce tree. Is that going to pose a problem with the chickens picking at the needles with all the acid and stuff? I haven't a clue so that's why I'm wondering.
