The vein is still very close to the tip. You may decide to file them instead of clip. My birds are so active that I have never felt it necessary to clip or file their nails. If possible, do not expose your baby to other birds outside your home. He is still very young and susceptible to picking up bacteria, viruses, or parasites.
Birds can bleed to death very easily.
Take your baby to the vet at once if it breaks a feather and you cannot stop the bleeding. A broken blood feather needs to be removed. This helps to assure that no infection will set in. Give him a bowl of fresh water each day and he will bath himself. If he is not bathing, turn on the vacuum cleaner.
