I started about 2 weeks ago putting apple cider vinegar (with mother) in my chickens water bowl and today I noticed that in one of my EE"s bantams poop was little hair like worms will the ACV kill or make a chicken with worms get rid of them do I need to worm all of my chickens I have 10 1 year old hens 4- 4 month old pullets and one 5 month old rooster should I go ahead and de-worm them and how should I use the medicine that goes in their water first followed by the other medicine that goes on the skin should I also use the DE, or should I just go to the one medicine that goes on the skin this is my 1st year with chickens and I have not seen any worms before also all of my chickens are of good weight for their size I have been picking them up just to check so any help would be appreciated I have read a bunch of post and it gets really confusing on which medicine to use and when I asked the guy I got them from about what I needed to do and he said not to worry about worms so I did not realize that I needed to be worming them twice a year plus how long can we not eat the eggs for. also do I need to de-worm them all at the same time or can I divide the flock up so we still have some eggs?
