We picked up these 5 beautiful young hens yesterday from The Lind Family Farm north of Frederick MD yesterday. They have an awesome set up. Mr. Lind prides himself on having a non- medicated flock. Problem is, I have had an issue with sick chickens recently. Should I medicate the new birds? Or wait and see? They are only 3 weeks, and are being kept in a desperate area until they get a little bigger. Thanks for any advice!
