My chicks are 3 weeks old and I gave them some "outside time" yesterday as the weather was very warm and I feel like they are cooped up in their brooder! They got to meet the dog and the cat. Our golden retriever Bolt was very curious and excited, but the cat was nervous (and made me nervous!) We held her collar as she let the chickens walk all around her. Im hoping the cat will get more comfortable, but the dog was great, so partial success! This is my first time having chicks and I hope to have a peaceful backyard.
