We own a large barn in upstate NY. The winters can be harsh. We are looking to build a coop inside the barn with a run. They will also be able to go outside and for now will have an enclosed run. If it works out they will free range and share a pasture with 7 Female Alpaca. We have one existing block wall and ceiling and want to build something inside that will allow them to be warm enough in the below zero weather we sometimes have. I have looked through a number of threads and photos and I’m not really seeing anything that is enclosed inside. The barn is old as we are working on filling in any holes with mortar. We are going to build a pen for the Alpaca right next to the chicken pen. Right now the Alpacas are set up for food, water, and bedding in the area that will be penned in and they stick to it really well even though we haven’t built the pens yet. The chickens and alpacas will be the only animals in the barn this winter. The barn has three parts as it was built in 3 different decades. I am using the newer portion. Will anyone point me in a more specific direction as to what we need to build? We would like to order rough cut 2x10’s from the Amish this week so that we can build their area this weekend as they are getting to big for their brooder. It doesn’t need to be pretty, just functional. Their area will be from It’s after that first window past the second window. Please help!
