Hey folks. I'm new to this chicken keeping lark, so new that mine are still on order. I've repurposed a shed and built a run for my birds but someone made a passing comment that the run looked a bit low.... It's 2ft tall at its lowest, because it's built on a slope an 3 ft as it comes out the coup. Is this enough room? My idea is that they will be able to free range around the garden as much as possible but obviously not when we're not around. The coup is 5ft x 6ft and 7ft high. Run is 12ft x 6ft and between 2-3ft high Plan is its to suit 4 chickens. If i have to build bigger I will, but any tips/pointers are appreciated. Of you guys think that's enough space that's dandy too. Medlgr.
