I build a chicken coop (work in progress) for my children's pet bantam chickens. Because of space restrictions I built a two storey coop each floor is 600 mm High, 900 mm Wide and 900 mm Deep, so all together it's 1200mm high. I am thinking of buying two standard size chickens (Australorps).
The coop is seating on the ground and I am planning in building two nest boxes on each floor hanging of the walls and lifting the coop up off the ground by another 600 mm, chicken access to the inside will be via doors from the outside one on each floor.
So my question is...will the top floor door be too high at 1200 mm off the ground?
