I love my ChickenGuard extreme unit its the most expensive addition to the coop but well worth the money especially when we go away not having to worry about a neighbour to check on the girls every night.
Thank you Michael for your kind reply.
Since my last post the little lady has regenerated new feathers, surprisingly only within a matter of days... her back is now looking like a porcupine. I read in another post to keep her protein up so she has been given special treats of cheddar cheese...
My Silver Laced has lost her a large chunk of feathers this week too.
She is ~15 months old.
I grew up with Leghorns and don't ever recall them losing so many feathers in one hit.
Is this common for Wyandottes?
Here is a picture of her.
