Hello! I am new here. I have 5 pekin ducks born around March 2013. They were all doing well until almost full grown and we started noticing one female didn't want to leave the pond and would call for the others to come back when they all would start heading for their coop at night. She was having trouble walking. It looks like she was bow legged. We have never really figured out where the problem is. We carry her up to coop and she lays flat and hides under the feeder box. She eats and drinks and is laying eggs with the other 2 females. The male ducks jump on her first when they can. It makes me so mad!! They pick on here I think because she's lame. We feed them whats recommended and all seem healthy but not overweight. Well, for a heavy duck breed that is. She does love the water though and seems just find while in the water. She is getting dull feathers and they don't look clean. We feel so bad for her and are at a loss on what to do. Can she be healed? No, we aren't giving any vitamins. I just read here about the niacin and are going to try that but is that gonna help her now? Should we (gulp) put her out of her misery? Another question, it's just now getting cold here and though they have a nice sturdy, hay filled shelter that we have tried to keep out drafts, can they handle the cold? We live in south Virginia. Any help would be appreciated. Thank you!
