@casportpony, I will pull her matching symptoms from your list.
• swelling in abdominal cavity (slight)
• limping (slight) it’s more like walking gingerly, like I said before
• roosting early - sort of... she could not get up there
• I would not say she has stopped eating and drinking, but her appetite is reduced
• hanging out alone
• vocal changes (not vocalizing like normal)
• sits when others are not (LOTS of this)
• last night she was panting/ open mouth breathing, but have not seen it today and today is quite warm
• change in laying habits (hasn’t laid over the three day weekend, but is only one year old)
As you can see, nothing by itself is overly concerning, but I know my girl and she is WAY off. Thankfully, she does not seem worse than yesterday, which is what I was panicking about... thought she was declining rapidly.
