The Corid is very safe, so don't worry too much if she gets a little more than she needs. At 200 grams I'd say she's definetly on the small side, and I would think that the others would be bigger, too. Corid is bitter, so you could try mixing their crumbles with the medicated water and that might help get more medication into them.
Now that you have a scale I think it's a good idea to track their weight. Definetly wat the small one daily, any weigh the others every few days. I have found it helps to weigh them at about the same time ever morning before their crops are too full (full crops give artificially high readings).
Can you post some pictures of their poop? Oddities in poop I look for are mucus, change in odor, odd colors, intestinal lining (slimy) and of course blood.
