I recently picked up these two girls. They are about 13 weeks old. They are both supposed to be golden laced Wyandottes. As you can see from the pictures, one is much lighter gold and the other one is darker. Is it normal for them to vary like this? The man I got them from said they were both golden laced Wyandotte's, one was just a lighter shade. Do they vary in how light or dark the gold is? I like them both either way, but just curious. Here are the pictures. Thanks in advance!
