No, there’s nothing wrong with this hen. She’s just stretching to soak up as much sunshine as possible. When hens are out soaking up the sun, they’ll stretch their legs out and contort their bodies into hilarious positions. From what I’ve observed during eight years of keeping chickens is that time out in the sunshine is a necessity. Chickens really need lots of space to lay great eggs, and they need lots of time out in the sun.
So how do hens in a cage-free laying barn like that pictured below get to have their time out in the sun? They don’t, and neither do most of the hens who lay those cage free eggs you see in the supermarkets.
