Hi I'm a 1st timer here. The mother is plucking the feathers from the head ,neck and chest area of her 3 little babies. they are weeks . She doesn't pluck any of the big feathers just the small ones .Does any one know why she is doing this . And is 5 weeks old enough for me to put the babies in another cage and can they eat on their own. They are still being feed by their parents . Help please!!!
