Hi, I am new to Backyard Chickens and even newer to raising chickens! We finished our coop on Sunday and soon after bought four light Sussex hens. They are delightful - I am in love with them already - but I can't tell them apart! We spent a lot of time discussing names for our girls, but now can't allocate names when we don't know which is which! How do we do it? This may be a really silly question, but please be kind as I am such a newbie to chicken rearing.
