The Size Of Your Entrance Hole !!!
What is the most attractive size of the entrance hole in a BH???
These answers might be something that you should consider:
1) If you have a new BH, the bigger the better.
2) If your BH is already with a sizable number of birds, you might want to reduce the size to an optimum.
For reason number 1) given, I would like to say that this is very crucial. Since there are no other birds going in or coming out yet, all new birds feel rather unsafe to enter.
Please take note, when I say entrance hole I mean the hole that you placed between the roving area and the opening where the birds are flying in. It could be between the roving and the pool room (the open roof method) or the roving and the outside (for dog kennel type).
They are still not used with the new BH and feel trap with a small entrance hole.
What I suggest is to have an opening as big as a normal door of 5'wide X 10'high.
Make sure you design as such that you can close half the door once your BH have at least 500 nests.
For item 2), once your BH is pretty filled with the nests, say 500 of them, you can actually reduce the hole size to slightly smaller then 5' X 10'.
I suggest that you reduce the size by half, at least.
You should never reduce the size in one go but by stages. Remember if you do then there will be a lot of dead birds on the floor.
The disadvantage of having too big an entrance is difficulties in stabilizing your BH internal air temperature and humidity. This is something that you have to take a careful thought.
However if there the humidity and temperature are perfect but not a single birds bother to enter the house, then it is better to opt for a larger entrance hole.
You need them to enter and populate your BH first then you control the humidity and temperatures.
So if you think about this article carefully you will be able to understand why your BH currently after being in operation for months but not one birds wanted to enter.
Learn something and apply them carefully and I hope there will been an immediate increase in numbers of birds populating your new BH.
