I received 4, 5-6 week old chicks yesterday morning. 2 Easter Eggers and 2 Barred Rocks. I ordered from a hatchery and they were shipped USPS. When I put them in the temporary coop yesterday. They all were eating and seemed to be well. Yesterday afternoon they seemed to be well also, and the waterer level had dropped a good 3-4 inches, so I assume they were all drinking. Later in the evening both BRs appeared like they were ready to sleep, and did close their eyes as my daughter and I sat and watched them. The EEs seemed to have more energy than the BRs. This morning, I went in to the garage, and opened both doors to air it out. I cleaned the feeder, and refilled (Using Nutrena Starter-Grower). Both EEs were fluttering around the coop, scratching, eating, and drinking. One of the BRs was eating and drinking, but not as rambunctiously as the EEs. The other BR was puffed up and didn't move. I reached in to stroke it's back and it moved slightly. I moved it next to the feeder, and it would lower its head toward the dish, but not eat. 20 minutes later, I looked in prior to leaving for work, and the BR was still next to the feeder, puffed up, with eyes closed. I picked it up, it didn't resist at all. I looked her over, and noticed a small amount of white, I assume poop, on the feathers by her vent. It wasn't a lot, just a small amount along the edge of a few of the feathers. Do you think this BR is having issues. Could it be from 2 days of shipping in a box?
