I always say don't count the birds count the number of nests which is more accurate.
But if you have a farm like the Video below it doesn't matter which one you count. By looking at how the birds going into the farm it already tells the number of nests in the farm.
15 or more birds entering the farm per each second. There are 60 seconds per minute. The birds entering the farm continuous for more than 20 minute. Imagine how many birds would there be? Take a calculator and count you would be surprised to know the number of birds in the farm.
Well that is very common to us but for some who are new in Swiftlet farming this could be shocking.
Enjoy the Video.
每秒钟有至少15隻或更多的燕子进入燕屋農場。每分鐘有60秒。 燕子不断的进入燕屋農場連續的超过20分鐘。 想像下有多少隻燕子在那裡？ 那出計算机来算一算在燕屋農場的燕子您將很惊奇知道燕子的数量。
( the Camcorder couldn't capture clearly as the speed of the birds entering the farm is too fast)
Good Swiftlet Farming All!
