Justin your box is full
Calf mana is good but in very small amounts, it can cause diarrhea.I used it for years.
I'd just try tums, and vit C tablets. Rose hips are good for Vit c, if you chins like them. Mine don't, so I just give them , the Mom's a 1/4 of each every 2-3 days. I also give them alfalfa hay. Kits like it too and will start eating it in days of birth.
Every one uses something different because all our chins have different tastes, and we all have access to different stuff.
Most do fine with nothing, if their from good breeds. It's just to make sure.
I did loose a mom after 4 years of breeding when her calcium depleted. Her teeth turned white, and no matter what I did after the fact it didn't help. So now I just keep the tablets in their cages. Some will just pick at them while some gobble them up. At least I'm trying my best.
