Defeathering and abnormal feathers in budgie chicks
Hello,
My chicks up to 15-20 days have good feathers (primary and secondary feathers was grown) but from this days their feathers specially secondary and primary feathers begin to drop and grow abnormal feathers or small feathers or don’t grow feathers at all.
Until now I have 12 affected chicks.
I take PCR test of PBFD two times and became negative.
Please help me
Thank you
