Hello! So recently I had to give my two chickens away since we are moving next week. We gave them to a very nice family who we knew would take good care of them. Casper(the younger hen, about 1yr old) was perfectly fine with the move and started laying eggs about two days after the move. Sadly, the older one (Jupiter) died the first night there. This is where I'm confused. We got her from a man we gave our rooster to. We do/did not know her breed or age, or anything else(she was not laying eggs). She was kinda scruffy. So about five days before we gave them away, Jupiter started having very watery poops. We did not notice it until a couple days later, and we thought she was just very thirsty (since it is summer here). We really did not know what to do(I feel bad about this), and we were already busy with the move. And another thing, she was starting to have featherless patches. So the people came and took them, but a little less than a week after the family notified us Jupiter did not make I really want to know what could've happened. I am very sad about it and I feel like her blood is on my hands, since I really did not do much about it. Do you guys know? What is an illness?
