Okay new developments, my call duck laid her first egg. I guess it was pushing up against her leg and that's why she was off on it. It is a pretty big egg with a soft shell. My call duck is still not any better and she's not eating. She's very weak and I'm worried. She is drinking tho.
She needs more calcium. I give my four pound duck an extra 100 mg calcium citrate twice a day for this kind of thing. So perhaps a Call duck person can confirm if 25 mg calcium citrate twice a day for a fee days might be worth a try.
