I have a blue silkie hen sitting on eggs. When I looked in on her yesterday, I noticed some broken eggs and I couldn't see her head. I moved her off the nest to the floor of the coop and she started flipping around and backing up and acts like she can't lift her head up. I've seen chicks with wry neck do this flippin backwards before but never a hen. What can I do for her? I put her in a wire cage to take the broodiness away and gave her some Polyvisol that I give to chicks...what else can I do?
