If the boys were over breeding her they may have hurt her back, they are pretty hefty especially if they are mating out of water, It may take a while for her to get over what may have happened. Are you giving her any support like Poultry vitamins/electrolytes or both. also swimming may help to take pressure off her leg and back plus give her some much needed therapy, warm water would be good. Keep her away form the Drakes even after you noticce her doing better or they may injure her again. Rest and some special TLC may bring her around if not then maybe a trip to the vets? Is she laying eggs?
This could be in her lower back and rest will probably take care of it. Also could be symptoms of egg binding, Is she laying? I know my boys are after the girls constantly. Sometimes I have to put them in separate parts of the yard to give the girls a break. Especially my older ones.I was thinking about running a warm bath for her but yea maybe over breeding, we try to monitor it but ducks are sneaky little critters.I will keep a close eye on her and not let the boys out when she's out and see what happens.
One thing you need to do for her is let her rest, that means she can exercise but not alot. try to keep her in a smaller area so she isn't using her leg alot. If she laid and egg then she is probably okay but keep an eye on that too. Warm soaks in water with vitamins like Poultry Nutri Drench and rest may be the best for her right now, and No visits from the drakes. Keep us updated on her progress please.
