Hello guys i don't know if this is the right place to ask this but as most of you know i have got 2 new cockatiels that i have had them for 4 months now and their wings were clipped at the shop on just their left wing and one of them is flying very well and loving life but the other one flied temporarily but now cant and has lost the ones in order to fly and have come out im not sure if they have been pulled/preened coz his moulting or how they came out in the first place but now he cant fly and he is frustrated and i feel very bad for him hes now back to being on the floor how long do i have to wait tell they are at full length.
