So this is my 2nd year keeping chickens. Last year was rough. I have a shed that I converted into a chicken coop but my Chickens rather sleep outside on top of there old smaller coop in trees or on our fence. Are there any tips or tricks to make them start sleeping inside ? I was thinking of locking them inside for a couple of days just so they get use to it is that a good idea ? Any advice would be greatly appreciated !!
