We purchased these 4 khaki Campbells on Mother's day. At that time they looked very similar. As they have grown however, 2 look like khakis but 2 are noticeably different. 1 has turned more and more grey and 1 is smaller, darker and stands taller. The little one looks like a runner to me. Are there grey khakis? Do hatcherys sometimes mix up babies?
Thanks for your help!
