The Small Classic Duck House has a sliding, meshed window on one side to control ventilation
The duck-size pop-hole door can be secured by folding up the ramp, it is closed with two bolts.
Access for cleaning is really good, not only do you have a large door at the back but one wall lifts off completely, the sides are interchangeable when assembling so you can choose which side to have your access panel (hooks will need re-positioning).
Overall external dimensions: approx. 1m x 1m x 1m high. Internally 91cm wide x 76cm deep x 92cm high (max). Pop-hole size: 31cm wide x 40cm high.
