1.. At 7 weeks he is very reliant on you & your family for his needs.He sees you as his flock, make the most of cuddle time, it is comforting for nike, he will soon enough be independent.
2..Babies make all kinds of mumbling noises,a happy content grey will grind their beak when resting/sleeping a bit like a human grinding their teeth.
3..Many people let their grey eat with them, they love to interact with the family & share dinner with you,it's a personal choice if you want nike at the dinner table, you can begin to offer a little human food, ie..veggies, After your baby reaches 7/ 8 weeks of age it is time to begin introducing weaning food.Pellet food is a safe food to start weaning your baby onto with the addition of seed,fruit, veggies.Also have a separate water dish next to his food.
4..try to distract from going under the cage, if the seed is empty he will only get the husks,& yes they can choke so close supervision.
5..Once Nike is fully feathered you can give him a little mist from a spray bottle,spray above his head & let the water fall down over him like raindrops
