Hi guys! I have a duck who has been having alot of laying issues this year. She appears to be egg bound once again (happened last month and did take her to the vet after she finally passed the egg because it had broken inside her). I have been able to feel the egg right there near her cloaca for a few days now, but she is starting to act off again. Still currently eating her favorite things (worms, snails, and corn) but will not eat her pellets (this is exactly what she did last time). I was able to get some calcium tablets (500mg), but how much and how often should I give it to her to help her pass this egg (she is a 2kg duck)? Do I just do one dose and wait a whole day to give her another if she hasn't laid the egg yet? Or should I give more earlier if the first dose doesn't work within a certain amount of time? Is it possible to overdose on calcium, or is it just like other vitamins that just pass through the system if you get more than you need? Sorry for all the questions, just want to help my girl as much as I can!
