In a Real War of Battle raising a White flag means surrender and accepting defeat the whole Nation fall. In Swiftlet farming raising a Black Flag ( Black orchard net) means the whole Farm fail and fall.
If there are no problems there shouldn't be any Black flag. Obviously heat is a problem and these Bhs are not doing well.
It can't even meet the Basic requirements what more could it do to attract birds to stay and to make nests. I still see many Bhs facing the same problem over and over again and I bet it would continue.
Hello Swiftlet farmers! This is not the way to build Bh. Have you ever thought of the Micros when you build a Bh?
I often see this when I travel. It is sad to see this. After writing for many years providing information on my blog with the purposes of helping Swiftlet Farmers to understand how to build a good Bh yet there are still many Bhs raising Black flag. How come they never learned.
Sad..sad..sad..
Good Swiftlet farming All!
