I would aim for something bigger if I had even more space to work with, but these are small enough that I can move them around by myself as needed. For my flock of 10 birds it's about enough shelter (considering some birds stay out despite the weather conditions).Your shelters are much smaller than what I thought for chicken shelters. Chickens would probably feel cozier with low ceiling! I'll think about making something like that for my chickens too!
