The written directions state to slide out one or two of the roof panels for cleaning. Gives complete access to the main unit and I would assume I can clean out the nest boxes easily thru the access door over the nesting boxes.
Only thing I would have preferred is the roosts be higher in the unit and not so low. I may see if I can swap panels to create higher perches. Also would be nice if the perches could be round, as most of my birds prefer round roosts to square. I may see how they like it and modify that if they don’t.
