Imagine your BH fulfilled all the good animal husbandry practices with the right temperature and humidity plus proper darkness.
All you need are those birds to enter, carry out their inspection and begin to populate your BH without any interferences from any predators.
What are the available options to help in getting more birds to enter your BH and begin multiplying your nests population?
I do have some strange suggestions and try to think about it positively.
I call them as shock treatments.
1) Changing of External Sound.
Try to change your external sound every 6 months. The 6 months period will be long enough for a good sound to stay effective. At the same time the new young birds from your neighbors will be happy to come and visit your BH.
A few days ago a BH owner from Vietnam thank me for the latest sound that not only works well in his BH (more new nests formed during the short period) but it also last for many weeks now. Those birds were still flocking at his main entrance window.
I could not say much more but try to see this video clip after more than 3 weeks the activities seems to be nearly the same.
2) Force Harvesting.
I have been very vocal about applying this technique for many years now.
I know many animal activist will label me as a bad guy.
I am just a practical guy who will share my ideas on how to quickly populate your BH.
If you think you want to increase your nests population by 30% within 3 months go for it.
Try to carry out some sort of planning and if you can get someone who can help to look after those babies and hatch those raw eggs.
Now with my smart partnership venture with a local University we have a special center to hatch those eggs and take care of those young babies.
The force harvest technique is proven and I have been applying this technique in almost all BHs that I was asked to repair during the last few months.
We cannot tell for sure what actually happened. From some reliable sources it seems that when the force harvest operation were carried out those affected birds will not return home for a couple of days. It was though that they stay in your neighbors BHs and during that stay they manage to communicate the "loss of colony" matter. That causes a kind of reinforcement that will come over to immediately populate your BH.
You need to follow a number of rules. One of which is after carrying out your force harvest you must lock your BH doors for at least two - three months. Do not enter your BH until those new and old tenants lay their new set of eggs.
3) Shock Aroma Therapy.
The inclusion of aroma therapy as one of the shock treatment is something new.
The whole idea here is to find a suitable aroma which will initially make those birds to be scared of your BH but soon after will bring additional reinforcement to increase your nests population.
Not properly evaluated but there are a number of reports that I discovered that make me wanting to include this special treatment method.
First you need to have a reasonable number of nests in your BH. About 50 or more will be okay.
Once you have the aroma ready, you shut the water supply to your chicken coop humidifier.
Remove the water inside the water pan and replace it with your aroma. Pour about 250 ml into the pan and you then switch the water tap back to top up the water.
Switch your sensor or timer device and let the aroma be blown into the air.
This will make your tenants to start running out of the BH since they though that the new smell comes from another colony of birds.
The only way to get back into their BH is to bring some kind of reinforcement to help them to fight with the new colony.
This can be a challenging technique.
What if the rushed out and never return home?
You need to find the proper answer and I think they will return home since they know that your BH is the safest place to start their family.
4) Wet Your BH.
Compare between a wet floor and a dried floor BHs.
I can safely says that wet floor BHs stand a higher chance of getting its population multiplied.
Dried BHs have the tendency to experience nest population becoming stagnant or a reverse gear syndrome.
New birds tend to shy away from your BH while your own birds especially those young birds tend to choose other BHs closed to your BH.
Apply those wet floor system and flood the pool with water to the maximum level.
To avoid mosquito from breeding apply those insecticide that are soluble when sprinkle into the water.
At the same time try to spray pipe water onto your walls and other floor areas that were not covered by the wet floor.
You will be surprised to see what happen after your install these wet floor system.
Usually those young birds that were brought up in your BH will return home with their spouse to start building their nests.
