... with their wings clipped, how high can a chicken jump/try to fly? I am in the process of converting a greenhouse into a coop (don't have chickens yet) and want to use the entire 6x8 floor for the birdies and put in shelves in the upper half (about 3 1/2 - 4 feet high) to keep plants that I'm hardening off. Is that too short? Will the chicks be able to hop up on the shelves and destroy the plants? I haven't been able to find this answer yet. I'm still gathering all information I can about chickens, the proper coop, etc before we get some in the spring - so i'm prepared! Thanks in advance for answering my silly question.
