my ducks are 5 weeks old. Since I got a “duck package” I have 4 different duck varieties and can’t be totally sure what breed they are. I have one that has had a weird looking head since I got them. Seems healthy and happy and VERY social- we named him Aflac lol- just wondering if it’s a deformity, disease, or just the kind of duck he is- pictures if anyone can tell me anything
