Leg issue and bloody stools EMERGENCY

[Duckduckpoop]

Just over the last few days my Khaki Campbell has gotten sick. She started laying in the yard more than usual but seemed fine other wise, then the following day her gait looked off and we noticed her hock joint is swollen and warm and that she had green diarrhea. Today we came home to her anus leaking blood and found this (shell of an egg??) in her run with blood on it. We are getting her straight to the vet tomorrow morning but cannot do anything until then. Anyone have any ideas of would could be happening to her?

It looks like an unusual egg that may be a combination of collapsed egg membrane and lash material from salpingitis. I know more about chickens, and nothing about ducks. I would give a human calcium citrate with vitamin D tablet, or a Tums orally for the next few days. She may be feeling puny because of this reproductive problem. I would offer her usual feed and some mushy feed and scrambled egg now. Electrolytes may be helpful, but try to get her drinking. Hopefully a duck expert will chime in.
