My husband has been raising 4 Pekin ducks and 4 Muscoves and 4 Rouens in our fairly large bathtub so that he can eventually set them free on our Pond. We have thick rubber mats on the floor to make sure that it is not hard or uncomfortable for them. He feeds them twice a day and is constantly watering them. They are all about 5 weeks old. We have been them special food from the Poultry feed store. We have noticed that 2 of the Pekins are not walking on their 'feet' but look as if they are crawling around on their legs. One seems to have one leg longer than the other. I feel really bad for it as at times it seems to pivot around in cirles when it tries to stand and falls to the right a lot. I don't remeber this being the case 2 weeks ago but honestly my husband has been caring for them. The Pekin seemed to do worse after swimming. In addition when one of the other Pekins tries to walk it seems to step on its own foot and stumble as both feet turn inwards a lot. I have read on this site that the feed can have harmful ingredients so I will check this when I get home. We contacted a Vets office about the problem but he is on vacation until next week. We bought some Niacin to add to the feed after doing a web search on sites like this. We have also added Calcium to the food since I have read that this can be a problem too. I would give them antibiotics to see if this helped if I knew which one to get. I was wondering if anyone else has suggestions. We will try anything to help them. It breaks my heart to see these two ducks unable to walk properly. I fear that the will not do well when they are eventually released. My husband did raise 12 Pekins without any complications a couple of years ago and we take care of them on our pond year round. We were hoping to add to their family as they will not sit on their eggs when laid. Thank you.
