CAG feather dropping off

Hi brothers,

I am new to this forum.

Just got a one year old CAG few weeks back.

Recently I realised that it feathers easily drop off upon light stroke.(between 10-20 pieces per day. mixture of big and small feathers)

It diet are fresh boiled corn, long bean,seeds and some pellet.


Any advice from expert out there?

Thanks
