leaky nest door...
do you mean it's leaking in when you open it, or any time it rains?
my other coop (and this one will be) i have a 2" piece at the top of the slope joining the box, then hinge on lower section. the roof on the coop overlaps where the gap is, but it leaked when it got openned, so I took a scrap piece of water hose, sliced it down one side and screwed it to the roof sections, forming a U channel to divert water flowing into the hinged area, so now the water that leaked in now runs into the hose and out the sides and onto the ground... no more soggy hens.
and on a happy note, today I found my d'anvers in the doghouse (aka dorking coop, till the big one's done). she'd been laying in the regular nest box, so don't know why she decided to switch to the doghouse nest, but my dorking hen who had a hidden stash of eggs i found saturday laid her first egg in the nest today! the other dorking has been laying in the regular coop-nest pretty regularly... so "Owl" gets an extra goodie for showing the new girl 'the ropes' 8)
