Way to keep it simple. Makes me want to try. I also have 3 chickens and I would think that the shredded pine litter with the droppings would be OK to add to the pile. Another thing I would really like to know; we too now live in Southern California and are plannign to move (hopefully next year) to beautiful British Columbia. Looks like just what you did. How are you handling the weather change?
We like the weather. I don't mind the rain or the long dark winter days. Some people can't take it, others have no problem with PNW weather. If you move to the shadow of Olympic mountain range e.g. Sequim or Port Angeles, its actually pretty dry with less than 50 inches of rain while other areas will be getting nearly 300 inches of rain. So pick your place carefully. Oh just noticed that you are going th BC. Not sure about the weather up there. But it is pretty. If you get seasonal depression, you need to get yourself artificial daylight in your house. That helps a lot of people.
People here are really nice.
Pine litter and droppings are perfect for the compost. Just add kitchen waste and you're there. Citrus peel, avocado skins take a long time to break down. But they will. Egg shells, avocado seed, died out annuals all go into the pile.
