scroogie

Hi, im new to this site but need some info on a baby wood pigeon my cat left me as a present!!! I think its more of a fledgling and seems to be in good health.I have been feeding it via a syringe with mushed up cat biscuits and egg white,but i do need to physically open its beak to do this...i half expected him to do this himself when he gets hungry but obviously not. Any advice would be great...i will try and download a pic regards steve
