We have one (maybe 2) ducklings that have slight angel wing. They just started tipping out. We are currently feeding 18% feed with oatmeal mixed (to reduce the protein level) and brewers yeast. We have 6 ducklings, 5 weeks old. The 2 who have AW are both blue swedish. Wondering if anyone has had luck wrapping with vet wrap? And any suggestions for changing their diet?
