We have an order of chicks due to arrive in a few weeks. I've been reading on a couple of posts about worming chickens & now I have LOTS of questions! ~How often should you worm them? ~At what age should you start? ~Is there anything that is effective, but safe...........won't affect the eggs?? Most of what I've read talks about having to throw out the eggs for a couple of weeks. ~Do chickens get the same kinds of worms that dogs & cats do & people can get?? We have big indoor dogs (a German Shepherd & a Standard Poodle) & 1 cat, they've never had worms. I am super paranoid about intestinal, or any sort of internal parasite!!!! ICK!!! Thanks for any info!!
