"Pak Harry, what other ways can I populate my BH with more birds?"
Beside playing those attractive bird call sounds in your BH and making sure that your BH is in a proper shape what else can we do to increase your BH nests population?
I was going through some papers and books about swiftlet farming. I came across something interesting.
As you are well aware these swiftlets will breed three times a year. Each breeding cycle they will lay two eggs and each cluster will consist one male and one female.
If you take some effort to look closely at the two eggs you will notice some differences in its shape.
One egg will be round in shape and the other elongated. The round shape will produce a male chick while the oblong will produce female chick.
By nature the ratio is always 1:1 (male:female).
What if you increase the female producing eggs to let say 80:20 (80% female and 20%males)?
Example: You have 300 nests in your BH. Every cycle you will produce a total of 600 young birds. More often the ratio will be 300 males and 300 females. If you adopt a 80% female and 20% male you will now get 480 females and 120 males young birds. In a year you will get 1440 female and 360 males. You can imagine if all these 1440 stays and bring home a male partner each?
Why must if be more female?
The basis of producing more female is that these females will usually stays and multiply at home more then running away to a new BH. The males tends to move out and stays with their girl friend's house. This is nature.
So if you increase the female chicks populations for every cycle the chances to populate your BH become much easier and faster.
So how to increase the female population?
This will be answered in my next topic: "How To Choose Female Producing Eggs?"
