I have 2 white pekins and 3 rouen ducks that are 11 weeks old. There kinda skidish and only come near me when i dont move or when i have food and there hungry.
Yes, I would say it's normal. Most of mine like to stay well away from me. But the more you are around them, the more they will get use to you. I have some that I am around quite a bit that barely get out of the way now.
