She may just be caring for the chick. She probably grabs food and then gives it to the chick, whilst caring for it.

Yes, just make sure you have something to keep the chick's legs from slipping and getting splayed legs.

It's possible that his wings are clipped from the breeder/shop, or they may be broken.

They appear to be two males, about 3-4 months.

Male

I learned the hard way not to count you chicks before they hatch. I had a red budgie, but she was actually sick with improper circulation, causing her feathers to be red. She, unfortunetly, died.

oh try candling them

probably the eggs died. sorry

I explained a one week process here.

Sorry I really like rainbow budgies, rereading this and I sound like an enthusiastic eight-year-old...

I would help out in the pet shop for the longest time, and the budgies were very scared and not hand-tamed. They would run to the other side of the cage whenever and human came by (they were clipped) and parents would let their kids grab them roughly. I decided to try to hand tame them, and developed a "formula". Day one: take some millet, and sprinkle the chunks (not on the stick) onto the cage, chill there, and leave. Do not attempt to grab them. Day three: Wait by their cage so they're used to you, and repeat the process. Day four: Same as day three. Day five: Wait by their cage for a minute,with your hand in it. Once they relax, put some millet in your hand and wait for them to eat it. Keep it in your hand, and make no sudden movements. Day six: Same as day five, but get farther from them. Day seven: Start teaching them to step up. Make sure no one comes up and scares them, or you may have to start over. Hope this helps!

She most likely steped on something, but better safe than sorry. You should put a bandage on it, and trim the nails to prevent in-growth. Also, please reduce your font size. Its rather distracting.

You should take him to the vet

UPDATE! We went out for christmas lunch, and when we came back Magic was curled up, and unresponsive. We rushed her to the vet, and she had a mutation that caused her feathers to turn red from blood vessels. She unfortunantly passed away, and I am not breeding them again. RIP magic

"Show budgies" are a human term. They are just regular budgies with fancy markings. The "normal" and the "show" will be fine.
