It has been 30 years since I have had the pleasure of keeping chickens. Now that I am on an off grid permaculture homestead I want to have chickens again! We have an outbuilding we want to convert into a chicken coop. There is a very large cedar tree next to it. Is that going to be a problem for the chickens? any toxicity issues etc? I am hoping it will create some much needed shade in the hot summer. Thanks... I am so excited!!!
