The Inter hole is small. Well to others it is sufficient. Like I had said before, the are many Sifus with many opinions. But my opinion is based of fact, research and experience. Observing from the picture, the width of the Interhole is 6 ft ( based on the partitioning). Actual fact it is not 6ft. It is only 3 ft. the other 3 ft taken or being used as a staircase. So a 3ft wide Interhole is a dead hole. Birds flying down to lower floor because they don't have a choice. Once they have observed the whole farm they will fly out and never return.
Well, from only 4 pictures there are already so many errors If I visit this Swiftlet farm I think I could file up a whole book .....(with all problems and errors).
That's all for now.
Good Swiftlet Farming All!
