I'd recently noticed one of my ladies (plymouth barred rocks) acting very stand-off'ish from the group and and generally looking depressed. Didn't seem to be egg bound, so I thought maybe she hurt herself jumping around they way they do after a bug or something. She does seem to eat a bit, but doesn't have much enthusiasm for the process. Then her comb seemed to be more floppy than usual and duller. She also seems to weigh less than the other ladies. Doing a lot of research, it seems to me that she might have worms. I've had the ladies since April when they were 4 weeks old and not wormed them since I wasn't aware it needed to be done regularly being new to owning chickens and never having worm issues with my parrots. I bought a bottle of Wasine 17 and know I'll have to forego eggs for a couple of weeks, but hoping this will get everyone 'clean' and then I'll switch to an natural product like WormGurad Plus (mostly DE) to prevent future infestations. However, I'm unsure of the dosage, being that is says to treat 100 birds with 4 oz in 2 gallons of water. I only have 5 birds. How would I dose that out?
