Hello, Hopefully someone on here can help me out since I feel trapped in a corner and I'm not sure what to do next. I got 2 male Pekin ducks on December 21st, but after close examination we feel that one may be a female, they are also strictly indoor ducks for now. We thought one of them was sick when they were about 3-4 weeks old so we took both of them to the vet to be checked out and the vet prescribed an antibiotic, which seemed to do the trick and they were both perky and eating loads of food. Recently this past Monday (Feb 15th) my boyfriend came home and let them out, they both came sprinting out to get cuddles and treats. He noticed one of them (the female we thought was sick a few weeks ago) got off his lap and spread her wings, so he picked her up and she walked into their area to eat. When I came home from work a few hours later I opened the pen to let them out and noticed the female couldn't walk at all, she was spreading her wings to walk. So we were both freaking out and put them in the bath and she would swim around but not move/wasn't as perky as the day before, when we took her out of the bath we noticed tear drops coming out of her eyes. She couldn't stand so we dried her with a blowdryer and we kept her separated from the other duck in a crate to sleep. We called the vet and were able to get in the next morning (Tuesday), the vet said she looked ok but we showed her the poor thing couldn't walk so we got x-rays, bloodwork, and fecal matter tests done, the vet never prescribed anything to us and said the x-ray was fine. The next day my boyfriend took care of them and she didn't really move/eat much but was drinking a ton of water, but she would eat treats, just not her normal food. Thursday we both had class/work so we kept the ducks separated and when I came home I just cleaned their area and made sure she was drinking water but she still wasn't eating much. When my boyfriend came home we put them in the bath together and the poor thing still wasn't being as active. When we took them out my boyfriend picked up the duck and he felt a small pop in her right leg and instantly she was standing up and able to preen a little bit but she couldn't walk much. Keep in mind this entire time we still haven't received a phone call from the vet about the bloodwork. They are still separated at this point. Friday we both had work again so when I got home she was walking more/drinking, but still didn't have a huge appetite. But she was being lovable, was able to preen herself, and even walking/talking. When my boyfriend got home he told me the vet called and said everything came back normal, that her calcium may be a bit too low (.5%) but the vet said the duck looked perfectly healthy, my boyfriend told the vet what happened about the pop and the vet seemed clueless and had no idea what to tell him but she tried to tell him to get antibiotics/some shot/some packets (keep in mind we already spent almost 500$ on all the tests and got 0 answers). The vet is suppose to be an avian specialist in our area. We decided to put the ducks back together so they could socialize and cuddle. Today (Feb 20) I was home and they both seemed great, it seemed she was on a recovery path, but she still hasn't eaten much, just nibbled a bit (it looks like she lost weight). I left to run errands and when my boyfriend came home from work he noticed the female was laying down again and COULDN'T walk again! I'm not sure if maybe the male is trying to mate with her and hurts her (they turn 2 months tonight). It looks like this time it's her LEFT leg instead of the RIGHT one that my boyfriend felt pop. I'm not exactly sure what to do next, they get niacin in their water with multivitamins/electrolytes, they get chic starter and are slowly transitioning to pellets, the treats are a bag of random veggies and they get kale/broccoli with their water and other veggies as well. Is the male beating her up or something, he's HUGE compared to her, should i try epsom salt with the bath? Please someone help us, we love these animals to death and would do anything for them.
