All this while have been looking for a way to weigh my birds and to know their weight per one because they have almost gotten to point of sales. So I did a random sampling I pick the smallest among them and the biggest size and some that are of average size.
Some weigh 2.5kg which is biggest size and the smallest size is 1.9kg and other weigh 2kg but averagely they are 2.3kg.
Which means they weight is okay and most the people who buy from me mostly they buy 2kg upwards.
