Either Safeguard (fenbenazole is the ingredient, same as Panacur), cheapest option is the horse dewormer, just use a small pea-size amount. 1 tube is for 1,250 lb of animal. Effective for tapeworm is Zimecterin Plus (again for horses), ingredients ivermectin plus praziquantel (that's for tapeworm). I use these for all critters, from kitten to chicken/turkey, sheep, dogs and the deer. The stuff must be terrible tasting though. Each animal HATES it, the cats and dogs start salivating to get rid of the taste, the deer wouldn't eat the apple slice with the stuff on it. Had to fix several "sandwiches" (appleslices with dewormer between them). On fawn I'd just take small amount on my fingertip and smear it unto their tongue. Both products available at TSC, about $10. My sheep readily take the safeguard alfalfa cattle pellets, but it's a little higher and can't be dosaged properly.
Glad to hear the little ones are doing better!
