My 2 year old hen just sit down and can't go anywhere. If I stand her up, she stands, but won't walk. I kept her in the porch all day... and she never got up to walk. She's eating & drinking.... and pooping! Looks good... acts good. She's not in distress & I touch her leg & hip with no problem. I took her out in the grass at dark. He wanted to head the the coop, took about 5 steps and laid down... and stayed there. I'm assuming to just keep her with me for a few days? Not sure what happened?
