Many had asked my opinion which is the best type, Open roof or Dog kennel? Well my answer is both. Both have their advantages.
It depends on the location of the farm. The common answer by many would be "if the majority in that area is DK then one should follow ".
That makes sense but there are many other factors needed to be considered before making the final decision.
Some of the factors are, wind condition, existing/old successful farms, light, etc. As I could observe more and more people prefer OR sighted reason of reducing noise pollution and there are more successful farms of OR than DK. That would be wise. But what we want here is to build a successful farm and sound pollution is secondary.
For sure one thing not known by many OR biggest advantage is that it has room for error. It accommodated the mistake/error made especial in relation to flying path. That is the biggest advantage over DK.
Whereas for DK the placement and size of entrance hole have to be very precise in order to create a good flying path.
So the conclusions are: a) if you yet to understand the flying path and wanted to start a farm then choosing OR would help.
b) If you understand the flying path well then you could choose anyone to your advantage.
