I have a hen this morning that is unable to get up completely and walk. She was able to get out of the coop and to the run for water. The other symptom she is showing over the past few days was I noticed she drinks a lot, very thirsty. I have brought her inside and given her electrolytes in her water incase it's heat related. She wasn't panting when I found her and she was able to get up a little and move when I reached for her, so she isn't completely paralyzed. I do want to add that this past weekend we removed all the straw from the run. It had rained very hard here and was a soaking wet mess. I sprinkled it down with Sweet PDZ yesterday morning. We will be using sand to replace it. However, I hope I didn't stir up something nasty when we were removing all of it. Any ideas on what could be going on with her?
