Hello everyone! I went to my brother's flock yesterday and pulled out one of the hens because she was not standing and her wings were stretched out completely. I noticed she was not acting normal like the rest and she was not eating. We put her in a separate pen away from the flock and she started standing last night and ate a little. I came back to check on her at 4:30 and she was dead and very stiff. I am assuming she died at 10 or 11, but I don't know why. Can anyone guess or make an assumption? I am going to continue searching.
