My 3 chickens are 16 weeks old. they have never been on medicated food or anything. I use small amounts of DE in their bedding and sometimes give them yogurt and garlic adn apple cider vinegar (people on BYC told me to do this sometimes) as preventative measures. They have never had worms and they seem very healthy and I hope happy. Also, I check their poo regularally and it is clean. I was just wondering if I am ever supposed to deworm (with medication) them even though there are no signs of worms? Just to be "carefull"? Just wondering. They will be laying soon and want to make sure we wont find worms or there are some gross things I should be aware of considering they have never been on medicated anything. Thansk!
