Wow I would have not thought to do that but sure enough she had an infection. There was nothing to indicate it...her health was fine, nothing saying she was sick, etc. At the same time I was treating her, one of the kids had a tummy ache. I gave him pepto and he popped up and ran off like he was fine. Out of curiosity I did a Dr. consult on him and he had a serious infection! I treated him and got the cured a gravely ill trophy. So I guess each time we get a sick peep it is worth it to check for infection in addition to treating them.
