Hello! My husband and I received our first 3 chickens, 6wk old EEs, yesterday! We live in rural WI and have a 3 year old son. We are all very excited about the new additions to our family. This morning, my husband went to check on them and found one of them dead, head down between the planks between their coop and ladder. This chicken also snuck out after I placed them all in their coop as night fell, as they were huddled together under the ladder with eyes closed. I checked on them an hour later, to find her back down out of the coop and under the ladder, so I scooped her and put her back in. I'm sure she tried to get back down under the ladder, but instead he found her head down, feet stretched out, obviously passed. We are devastated. I know, this isn't a traditional intro post, but this is my intro to keeping hens. Do we need to cover these planks? They are three 2x4s with a gap of 1.5 inches between them. Is this a design flaw on our part or some kind of weird accident? She did seem more lethargic yesterday than the other two, I just chalked it up to her traveling overnight to us, but that wouldn't explain why she would keep leaving the coop after dark, would it? We are going as local as possible from now on in case the stress of travel played a role.
