Not at all impressed with the flimsy structure of the Gertrude. Gaps everywhere which makes the sliding vent redundant. Very very cheap thin wood, doubt this will last. Currently housing 10 chooks until I can build my own. Pulling out the tray with sawfilings/hemp one it drags it onto floor if it is more than 2 or3cm depth. Roosting bar holders are pinned on and so break, hinge points pinned on so also come away. Very very cheap and nasty. Wish I'd gone for a flytesofancy arc. Still in great condition after 8 years. This eggshell thing? Rubbish.
