Not many of us, who own BHs, will be bothered to ask our so call "Consultant" about the relevant of the BH humidity.
We tend to take it for granted. It must be 85% - 90% RH.
What the "Consultant" says will be like those words from the Prophets.
Well if you want to test how good is your "Consultant" you do this. Pick up your mobile phone and call your dear "Consultant".
As him : Why must the humidity be 85% - 95% RH?.
Some will tell you that that is the rule of the thumb and some might ask you not to ask too many questions.
The best answer that he might give to your question will be the effect of those water droplets in the air to make the nest stronger and not brittle.
Brittle nests will easily be broken and if those young birds cling on them will fall and die if their wings are not yet formed.
The next answer might be : The nest will be nicer in its shape. Smoother and rounded in shape. With too little water in the BH they will be wavy in form thus dropping the sale value.
To me that is not good enough.
The most important answer that he should give you is more towards the important of the proper humidity towards hatching of those precious eggs.
Before the birds decide to stay and build their nest in your new BH, they will check everything that will be ideal for them to start a family. One of the important thing in their list will be the proper humidity.
There is no use to lay their eggs and once hatched their babies are sick or distorted or deformed or crippled.
The ideal temperature and humidity to hatch eggs are said to be at 101*F (Still Air Technique) and about 60-75%RH. To be exact the humidity must be 60%RH for the first part of the incubation period and 70%-75% when the eggs are about to hatch.
What happen to the eggs/hatchling if the humidity is too low?
When your BH experience too low a humidity it will results in excessive evaporation, causing chicks to stick to the shell, remain in the pipped shells, and sometimes hatch crippled.
If you happened to use incubator to hatch the eggs, you do need to provide some container to store warm water to help in increasing the humidity.
There you go. Now you have a better idea on why Humidity is so important in your BH.
But why must it be 85% and above?
That will be something that you need to do some research.
Coming back to your "Consultant", if he do not know the right answers or gives you wrong answers, what should you do next? My advise is to terminate his service and find a new and more intelligent person. Maybe you should become your own "Consultant".
