how long for my macaw to grow back feathers on his head the mother plucked them in the nest box @2 weeks old?
You have to be a bird to grow feathers. humans don't grow feathers.
Yes, but the feathers will soon grow back.
no
About 3-4 months.
The tail feathers will grow back over time.
The tail feathers will grow back during the next molt. Do nothing and just let it be.
Yes. The long tail feather often drop off during the first molt when all the roosters feathers are replaced by new one's. The new long feathers will take more time to regrow so be patient, they will come back. Many roosters lose the long feathers due to picking from the hens while they roost at night
It may affect his steering in flight, but they will grow back.
