I found three feral chickens, one day old. Put them in a box. Went down to the tractor store to get supplies. They told me I had to get all these things to keep them alive. I live in the rainforest. But I just got the medicated feed & water containers. I live off grid I'm not going to put on a lamp. So that night I put the chickens next to my 85 lbs yellow Labrador Retriever. Inside on her bed. They slept their cozy and warm for 12 hours straight. Now a week old. But since I caught them feral and they were outside do I need to give them some other kind of medication also?
