Bird Room

The birdroom is fully alarmed, the alarm is also linked to the house. In the event it is actuated both the house and aviary sirens sound.		My aviary is of concrete block build and rendered, it is 18 ft long by 8ft wide. The aviary is fitted with UPVC windows and doors.
	*I have two extractor fans installed, one in the far wall and a large one fixed into the ceiling and vented outside, I find this keeps the atmosphere reasonably fresh.* *I also have 8 air vents and two large windows which are usually open all year round.*
