My almost 6 week old call duckling has drooping wings that seem to keep getting heavier. The other 4 from the hatch don't have this problem. I've been feeding duck crumble since they hatched and switched over to flock raiser at about 3-4 weeks old. I have been giving them mashed peas as a treat because I read there is niacin in them. Let me know what you think and the best way to wrap this little guy. The pictures I found have me a little confused on how to do it properly. I already have vet wrap here.
