My ducks and geese have been together the entire time I’ve had them and issues have started this week. My bigger to geese are picking on the smallest duckling and almost killed it today. These birds will be 4 weeks old on Friday and the ducks are 5 Peking and 1 crested Peking and the geese are 2 African Greys and 2 Toulouse. I looked up what might be causing it but I’m not sure what to do. I read it could be caused by boredom, being too hot, lack of space or a need for more protein. Please help me I isolated the duckling and not sure what to do besides let it heal. These are my fair projects for FFA and 4H please help me.
