WHat's wrong with my pullet?????

[coltsrox]

Howdy my 7 month old pullet has been laying eggs but all of a sudden stopped and I knew she was molting so I knew it was ok but now it looks like she may still be molting but she hasn't layed a egg in almost 3 weeks, and I found diarreha today in their cage. Could this be the dewormer i recently gave them?
Also how do i know if my chickens have worms?

Um, that's here. I dont know if your bird is still molting. Three weeks not laying isn't very long, actually. They can stop for an entire season sometimes, if they have a long molt.
