Many people do in fact use fish medications to treat their chickens orally. The clindimycin above is in 150 mg capsules, and that is way to much for a chicken. Some of the dosages I have read are 10 mg per every 2.2 lb twice a day, I have never used it. There are lower dosages in capsule form or drops available online with a prescription. Fish med companies can sell these online if they state they are only for fish.
