How High is too High?

Hi again, you were all so helpful when i asked about whether chucks would put themselves to bed and about my fox-proofing plans so I'm back! 

I have now decided to go ahead and get some lovely chucks - my eglu comes on Friday - took me ages to decide over eglu or trad house....and hubby and I are building the run Saturday morning with the hope of collecting my new lay-dees (sorry ) in the afternoon.  Anyway about the run - I was planning on building it approx 4.5 feet hight, sunk into the ground by 9-12 inches as recommended - with a wire roof also to prevent jumping foxes!  However is there really any need to build it this high - I was thinking it would be easier for raking and cleaning, but could I just hing the roof and have it say a metre high?

Agghhh so much to think about, but sooo exciting - I'll avoid the obvious pun on that one!

Thanks in advance all x

Aidy is right about you need to think how easy it will be to clean out, but if you've got a hinged roof that gives you easy access a metre high should be fine. You'd still have room to put a low branch in for them to perch on if you wanted to.
