ohh and to add, im getting ready to move mine outside into a bunny hutch we're no longer using and i fully plan on giving them a light. I gave my entire flock a heat light last winter in the coop for more comfortable sleeping. Not sure i'll be doing it this year yet it all depends on if i get them out of the temp coop or not as it isnt insulated at all and is made of metal shed materials. But i do not take kindly to others messing with my stuff. Even when my hubby comes home for a visit, he knows better than to mess with my birds. He values his life too much!!
