Hello Azhar, please note that this page can be only view by the link given in the email.
As you mention earlier, Unggas Sanctuary is a chicken farming business. I think to include feather or a chicken in the logo suits this matter very much.
So I have incorporate both feather and chicken with the initial “U” from the word Unggas to play around with the logo.
I have tried many combination color and find out green, orange, dark brown and red is the best combination to align the brand position.
The shape on the logo is quite bold so it will be easily recognised even printed out in black and white.
You also mention that your son will be taking over this business. So I have incorporate stars in the logo which suggest the excellency of you and your 3 other son to grow this business.
Lets have a look.
Option 1

Option 2
Notice that the negative space of the feather form the words “U”.
