While carrying out the revamp operation works I was a bit concerned over the ventilation holes of the BH.
First it was only made available on two floors and not the ground floor.
The second was that the holes were only on two walls and not all the four walls.
The thirds was the use of white colored PVC 4" diameter pipe that tend to brighten the nesting areas when those sun light hit on the building.
The total number of ventilation holes per floor (2 floors only) was about 20. 10 on the wall facing the west and 10 on the opposite wall.
The walls that faces the North and South were with not a single hole.
What make me wonder what was the contractor trying to do was on the ground floor there was not a single hole.
It might be okay if there are little number of nests however what happened when the floor is full?
Something that might be a disaster when the ammonia gas could not be taken out of the BH and replaced with fresh air.
A few years ago I was told about a BH in Vietnam that went through a bad experience.
This BH was said to be filled to the brim with nests.
For some unknown reason those birds start to die in hundreds.
The owner was scared that it was some kind diseases attacking his birds.
The health authorities claimed that those dead birds were healthy and the main culprit was the lack of fresh air.
Once more ventilation holes were opened the BH was back to normal.
So what do you think I did to the Ajil BH.
Due to limited time available I suggest to the BH owner to find out if there are any service to bore those ventilation holes using specialized machine.
Once they have located it they should try to engage the contractor to drill additional holes in about 6-10 months from the day the BH was put into operation.
I hope they will do that earlier especially if the nests number increased drastically.
