Allow me to jump back in here. A genetic defect is a feature, not a bug as in a temporary health glitch. It is not going to miraculously grow a lower beak. This chick will either figure out how to drink and eat or it will perish.
You can tube feed it water and food, but realize you will need to do that every hour all day long until the chick is around eight weeks old, and then you will need to do it around four times a days until the chick is four months old, then twice a day from that point on. The entire life of the chicken.
This is not practical or fair to the chick. Offer the moist food, continue to make water easily available, and if the chick learns to eat and drink, that will be super. But if the chick becomes weak from dehydration, you have a choice to watch it die slowly in agony, or to euthanize it so it need not suffer the slow death.
