If a baby owl loses its feathers will they grow back?
That depends on why it lost its feathers in the first place. See the site below for more information.
Yes, the feathers will grow back, but it takes time depending on how short you trimmed the birds feather or if the bird is shedding it will grow back too, but again, it takes time. *AuzzGirls answer* Thanks, but I didn't trim them. My budgie is a baby and her long tail feathers were ripped out, because she was climbing the wall of her cage with her tail feathers sticking out.
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
