1/2

I have this 2 budgies They are very small, no more than one month old. I separated them from their families because one of their families killed their third brother, and I could not risk their lives and to see which one of their families killing them in order to isolate him, so I separated them. Anyway, I was playing with this little boy and I decided to train him to stand on my finger I started training and it didn't take long. Within 30 minutes he learned how to stand on my finger But I noticed that his left foot is so weak that he barely uses it Compared to his sister, she uses both of her feets comfortably, while he relies on his right leg and i cannot take him to the vet because the nearest vet that can help budgies is 5 hours away by car, and I do not have a car at all, so I decided to rely on the expertise of local breeders. Some said I should move them to a smaller cage and give them an egg everyday , i did move them to a smaller one and i give them an egg every day , but what do you think? Any advice would help
