My husband and I have spent the day building a chicken coop out of Hay Bales, and we're trying to decide on how to incorporate a door into it. We were wondering if anyone has built a structure out of hay, and how they handled the door. (We have a large Wood-built chicken house, but the new spring chickens are getting "butted out" by the older chickens that have used it for 2 years, now. So, before cold weather hits, we're trying to get them out of roosting in trees (their preferred roosting spots) into warmer quarters. We have done an incredible job on the hay house, reinforcing it with rebar posts driven into the ground and tarps on the outside, but now we've got to figure out if an opening is sufficient or if we need to come out each night and lock them in. I've read the posts about how necessary doors are, just from the standpoint of predator protection, though we've never had much problem at all where we live (in the suburbs of a large metropolitan city). Our property is fully fenced, so the only possible predator would be a possum or racoon which could climb a fence (we've only seen a couple in the 5 years we've lived here.) There are roosting boxes in the hay house as well, so we need to leave enough room in the door frame (or at least leave it movable) so that we can get in each day to collect eggs. Can't find many hayhouses just googling the internet, so thought I'd ask for your feedback!
