I tried the liquid (crushed) antibiotic. Didn't go well. She fought tooth and NAIL once she got a taste - it took 3 syringes. I think I'll try splitting it twice and giving it in 2 solid chunks next time. I learned that the 2 homeopathics that work (they say for ectopic eggs) are Bryonia and Hepar Sulph. Don't know if they will work in combo with antibiotics. From reading I've done in the past the later can negate the homeopathics but that's a discussion for the homeopaths.
Thanks for your suggestions. I'm not sure why I am doing this though. I will not opt for the surgery, so if it doesn't pass (as it is apparently in the abdomen and I don't know if her stomach can digest and expell it), I assume she'll need to be put down at some point.
