WHICH IS THE BEST CORNER BOARD? " STAINLESS STEEL PLATE" 那一個是最好的壁角板 “不銹鋼板“

This is to prevent Swiftlets from building nests at the Wooden corner boards or the 90 degree corners (if the Swiftlet farms have yet to install any corner board). I prefer to Stainless  Steel plates because nests built on these  Stainless Steel plates edges are straighter… it is almost 180 degree. (Straight).

With Stainless steel plates,  the corner nests could be totally eliminated. The reason Swiftlet farms are using Wooden corner boards is to reduce the number of 90 degree nests that fetch a lower price. But Wooden corner board could only reduce the angle it cannot eliminate it totally.

Nests from the Wooden corner boards would still have a small degree of the curve at its back. This is due to the shape of the Wooden corner board especially the part that meets the plank.

To understand how it affects the shape of the nests, please see  illustrations below:

這是爲了防止燕子在木壁角板或90度的角落做燕窩（如果燕屋還未安裝任何壁角板）。我比較喜歡用不銹鋼板因為被做在這些不銹鋼板邊緣的燕窩是平直...它是幾乎180度(直)的。

有了不銹鋼板、 角落燕窩才能完全消除。燕屋農場使用木壁角板的原因是為了減少90度燕窩的數目，因爲它取得較低的價格。木的壁角板只是可以降低角度，但它不能完全消除它。

從木壁角板的燕窩在它的後面仍然有小程度的曲線。這是因為木壁角板的形狀的尤其是連接木板的部分。

若要瞭解它是如何影響燕窩的形狀，請參見下面的圖：

(( Previously nests were built on the wood corner boards. Now with Stainless Steel Plate nests are built right at the edges (lines) between the plank and the Stainless Steel plates)

(以前燕窩被做在木壁角板上了。現在用了不銹鋼板，燕窩被做在不銹鋼板和木板之間的邊緣（綫）上)是平直的...它是幾乎180度(直)的。

Above is the illustration of a straight Conner board. Straight corner boards were commonly used before the crescent type corner board. The sole reason is to prevent birds from making nests at the 90 degree corners. It did serve some purposes where it has reduced the angle, but nests collected from these straight corner boards are still considered 90 degree nests. The only advantage is that you could collect a heavier and bigger corner nest. They are widely used throughout the country. Left over planks  are cut and turned into corner boards. Nothing goes to waste, but labor intensity is needed to cut those planks. 

以上的説明是直的壁角板。在月牙型壁角板出現之前，直的壁角板是最常用的。唯一的原因是為了防止燕子在90度的角落做燕窩。它的確做了它的目的來減少角度，但是從這些直的壁角板所收集的燕窩仍然被認為是90度的燕窩。唯一的好處是你可以收集更重和更大的角落燕窩。這個產品在全國各地廣泛的應用。剩下的木板都被切割和轉換成壁角板。沒有東西是被浪費掉的，但是卻很費勞力來切割那些木板。

The Crescent corner boards came later. It reduces  the angle further but unable to 100% eliminate it.. The above picture  shows, the angle (red color), which is caused by the shape of the edge of the Crescent corner board. The crescent corner board works better than the Straight corner board. There is no hole or gap behind the Crescent corner board.

As for the Straight corner board, birds could still build nests in the hole (gap) at the back of the corner board. Furthermore, this is also a favorite place for cockroaches, lizard, etc. to hide.

之後，半月形的壁角板出現了。它進一步的減少了角度但是還是不夠100%的消除它......以上的圖片所示的角度（紅色），也是由半月形壁角板的邊緣引起的。半月形的壁角板比直的壁角板來得更好。半月形壁角板的背後沒有洞或差距。

至於直的壁角板，燕子仍然在壁角板的洞(差距)的後面做燕窩。此外，這也是蟑螂、壁虎等等最喜歡隱藏的地方。

Unlike both the Straight corner board and the Crescent corner board, the Stainless Steel plate virtually eliminate the existence of corner nests. Birds are unable to build nests in the middle of the plate as it is very slippery. Now Birds could only build nests on the lines (edges) between the plank and the plate. The angle is almost flat. Nests harvested  from these angles are considered straight nests and they fetch higher prices.

不好相這兩個直的壁角板和半月形壁角板、 不銹鋼板幾乎消除角落燕窩的存在。燕子是無法在銅板的中間做燕窩，因為它是很滑的。現在燕子只可以在木板與銅板之間的綫 (邊緣)上作燕窩。角度幾乎是平直的。從這些角度收穫的燕窩被視為直燕窩，他們可以獲取更高的價格。

A new nest is built at the edge of the newly install Stainless Steel Plate. By adopting this technique your Swiftlet farms will produce 100% straight nests.

一個新的燕窩被造在新安裝不銹鋼板上的邊緣。通過採用這種技術，您燕屋農場將生産 100%直的燕窩。 

(The other side of the corner is not covered with any corner board. When the babies have left

a Stainless Steel plate will be installed. There goes another corner nest).

（另一邊的角落沒有被蓋上任何壁角板。當小燕子離開的時候將安裝上不銹鋼板。又另外一個角落燕窩被去除掉)。

NOTE: PLEASE SPRAY LOVE POTION AFTER INSTALLATION OF STAINLESS STEEL PLATES. THIS IS TO ATTRACT BIRDS TO BUILD NEST ON THE PLATES.

注： 請在安裝不銹鋼板之後噴上Love Potion。這是為了吸引燕子到銅板上作燕窩。

Good Swiftlet farming All!

大家有好燕屋農場！
