Hi sweetie! Sorry, I often miss posts when I'm at work (12 hr shifts).

He needs electrolyte replacements if he's not eating. Use plain pedialyte 1 part to 10 parts dechlorinated luke warm water with 2 drops of honey in it. Soak him for 20 minutes in the mix with the water no deeper than his belly, less than his chin. Prepare a second plain dechlorinated water bath for a 15 minute soak to rinse the residue off of him.

Any idea of how long he hasn't eaten for?

I'm not sure what is ailing him. If you use the calcium daily, that's it's unlikely that its hypocalcemia. What brand of calcium do you use? Are any of the others sick?

Again, sorry for the delay .
