Yesterday, I went to the barn to check on everyone, and one of my female ducks just sat on the ground. I went over and tried to lift her off the ground and on her feet, and she could stand for a second, then sit briefly. I tried again multiple times and sometimes she would take a half-step, then sit again. I checked the pads of her feet, and they were clear of abrasions. She eats, drinks, and quacks fine. Here's some information on her... SPECIES: Pekin GENDER: Female AGE: 3 EATS: Chicken scratch, daily treats (tomatoes, bread, live minnows, grapes, exc.), and oyster shells EXTRA: Was limping a little but still got around fine, flock laying more eggs than usual I have put her in a dog kennel where she'll have easy access to food and water. I am very concerned about her issue, since the last duck I had who couldn't walk was crippled beyond what vets could do due to a mean drake (who is gone now) and was sadly euthanized. Sometimes the ducks act sick one day (example: narrowed eyes, droopy wings, sluggish), then are fine the next. She laid an egg today, so she is not egg bound. We have a coop and run, so they aren't exposed to much of nature except when I let them out while I'm there. PLEASE RESPOND ASAP.
