My friend who lives on a pasture has a ton of chickens. She has offered to let me catch some to add to my flock of 2, we use to have 3 but she is no longer with us. Her chickens are pretty wild, so any tips on how to catch them? And what should I look for in the chickens to make sure they're healthy? Also, when we introduce them to our 2, what should I do and expect. Were planning to get 5. Thanks!!
