Ok, our Pekins were recently attacked. We gave them each .5 CC Penicilin injections and washed their wounds with wound spray. When they were first attacked their feet and bills did feel hot and they were slower then usual, and our Pekin female, also named Daisy, had a head wound and acted slower and wouldn't eat for a day or two. After a week of twice daily antibiotic injection and twice daily wound spray, and alternating between giving them probiotic and electrolyte supplements in their water, they were both fine.
When we noticed they had hot feet and bill tonight, we gave each of them another antibiotic injection before we put them in their coop for the night. I haven't found anything on google either.
I posted an article earlier about how well our doctoring them has worked, unfortunately I'm afraid I may have posted too soon. There aren't any other symptoms, we're just worried because it's not their normal bill and feet temperature. Also, none of our 6 other ducks have this issue.
