I have an 8 month old EE who is not well this morning. She is puffed up, tail down, not eating, had a little to drink. Her crop is nice and small, I haven't seen any abnormal poops yet, Her tummy feels fine. Vent looks good, although it does open and close when I mess with it. I assume that's normal. She has had a few soft shell eggs in the past but laid a normal egg yesterday. Any ideas? She freaked out last time I brought her in the house, so I put her back in the coop and turned on the heat lamp. I offered scrambled egg, oatmeal, warm corn. No luck. What's next?
