My Ringneck doves aren't cooing

[FrostyWind]

Why aren't my doves cooing anymore? They are healthy, always practice their flight so they can keep stay in shape and feed them at a certain time (4:30pm), and they can come out the cage anytime they want and fly anywhere?

Soo why aren't they cooing regularly anymore?

May be because they are molting. During this time they use a lot of energy to replace all their feathers.

But I see no feathers in the cage or any feathers missing?
