Where we live there is an abundance of dry, fallen pine needles everywhere (east Texas). Being the eco savey chick I try to be, I had hoped to use them as a free alternative to pine shavings for the floor of the coop/run as well as bedding for the nest boxes. I will be using the deep litter method. I've searched the threads on this and can't seem to find a reliable answer. Some people say they have for years, others say they're laden with tics. What do you know about it?
