1. how long do worming meds keep working in a chicken...ie if they were wormed in january, would the wormer still be keeping them worm free in feb/march/april/may/june/july?? 2. how long does it take from first ingesting worm eggs to it becoming a full blown worm infestion/causes problem for the chicken with the worms? 3. do worming meds kill all types of worms or just certain ones (i have an 'all round wormer' but cant find what it kills in the leaflet inside? 4. what are the most commmon worms in chickens? 5. can worms really kill a chicken? 6. can a wormer be given the same time a chicken is on other medication and/or vitamins etc (ie anti biotics, acv etc) sorry for the questions but im curious as too how long wormers work etc..also is there any 'natural' things that help keep worms at bay? ive heard garlic is used but how is this given...crushed gloves? dried powder on their food? squished in their water???
