Hello, I'm a new backyard chicken owner. I've never had any hens before nor do i know that much about them. A few weeks ago i bought 4 hens from a farmer. I did quite a bit of research on the breeds i wanted. Based on his information i should have now: 16-17 week gold laced wyandotte 14-15 week black australorp and light Sussex 12-13 week white leghorn The leghorn is the hen i wanted most because I'm really looking forward to her large white eggs. In my eagerness i was trying to find out what 12 week leghorn would look like and based on some pictures I'm very confused as to whether i really do have a leghorn or not. Any confirmation as to the rough age and breed of these hens would be really appreciated. They're all very friendly and i live then to bits, but it would be nice to be sure of what I've actually got!! Thank you!
