One of my Speckledies has lost the use of her legs. We noticed it on Tuesday when she began sitting quietly in the coop rather than being in the garden. She spent the next 2 days sitting upright, like a dog but now is lying on her front with her legs splayed out behind her. We have tried to help her to stand but her legs just hang limply and she doesn't move them at all.
She looks bright enough; she is eating and drinking and her feathers look and feel in good condition.
Any ideas what could be wrong with her? The other 5 hens all seem fine.
