I'm thinking of making my nestboxes into external nest boxes so I won't have to go into the coop to get the eggs everyday. What is the best way to make it easy to clean if I do this? I was thinking of having it come on and off the coop, and for those of you who have nestboxes assembled this way, what is the best way to go about this? I don't want rain/varmints to get in and all through any gaps between the boxes and the coop. Thanks for the advice!
