We have 3 chickens and they're about 1 yr old. We've never wormed before and my Millie's odd "mute open mouth calls" today made me curious, so after some reading on here I think she (and therefore the other 2) has gapeworm! Ack!! Is it the pour on Ivermectin I have read about here that I need to use? Wazine only treats roundworm, am I right? Or should I still do round one with Wazine and round 2 with Ivermectin / whatever it is I need for gapeworm? I have one large fowl, and 2 itty bitty bantams. We're also bringing home one large size Ameraucana/Easter Egger tomorrow (going straight into quarantine and then slowly introduced). Should she be wormed with the others as well, she'll be around 7mths? Thanks!!
