Based on recommended numbers that size run would be the bare minimum for 6 birds, and the coop would technically need to be about 4x6, but I would go bigger as a personal preference...
That looks like this coop, at most 2 chickens in that coop... And beware most coop kit companies over rate their chicken count, best to take their suitable for chicken numbers and cut it in half...
