Yes i am not from the US..I CLEANED HIM HE'S DOING MUCH BETTER NOWYes, the directions on that bag should be about the same as what I stated although I'm not familiar with that formula. You are not in the US I assume?
Your sweetie has already been through some rough times. His formula/body temperature has not been consistent and that's why you see all the stress bars on his new feathers. He needs a stable routine. Babies that young should be kept pretty warm and not have a bunch of action going on around them.
Other than the beak question are you having any other issues? I think Brian answered how to remove the formula from his head. Just a warm washcloth.
