We picked up our 6wk old EEs yesterday morning. They all seemed lethargic after an overnight drive from mypetchicken to our post office. They all found their food and water ok, and as night fell I realized they weren't going to find their way into the coop. I scooped them up one by one and put them into the coop. I came out an hour later to check on them, and one of the ladies had found her way back out, and was huddled down under the ladder. I put her back into the coop. I thought it would be too dark now for her to try that again, so I didn't check on them again until this morning. My husband found one of our chickens feet up, head down between the planks, obviously passed away. Do you think this is a design flaw, and a weird accident? My husband is going to pick up a piece of wood to put over it to be safe. But I wonder, as this was the most noticeably lethargic chick, was she trying to separate herself because she knew it was coming? Or maybe she ventured out for food and a drink and fell between the boards and couldn't get out and froze. We are all devastated.
