I need help for my budgie im worried :(

so now im birdsitting my friends budgie's since theyre on vacation for a month. they are terrifyed of everyone and well I have budgies too and they keep climbing on their cage they want to play with them, but their birds wings arent clipped so they fly around really high but slower than my budgie.but my birds have been acting as if they were scared of us but we tamed them and care for them well, I really dont get it please help me, and also, my blue budgie is younger than my other one but its wings havent grown very well, they clipped her wings way to much and she flies off but she falls down hard and sometimes her feather come out and some have blood! im really worried, ive been planning on keeping her on the cage until her wings grow so she stops getting hurt and like leave her insinde the cage and not let her out until her feathers grow because she gets really hurt so please im begging you to help me please, those people who cut her wings cute it badly she barely flies 40 cm! ok bye and please help me thanks bye ;)

I suggest telling this to the owners. And I wouldn't keep it in the cage for long, because then it will over preen and make it worse. Try piling old blankets under where you let them fly around, so it won't get hurt if it falls. hope this helped! ~Rose
