I had brewers yeast here and I completely forgot to tell hubby to add it. By a week old could not having it kill them? Or is it more likely that a dirty brooder caused her to die? Or just randomness. My husband lost one east Indie while I was gone but it was the day after shipping so I attributed it to that. Storm was fine until this morning apparently running around with the rest. My 3 remaining EI seem great. Running, jumping, eating, drinking, pooping, and sleeping but now I'm worried. I completely emptied out brooder, disinfected it and everything in it. I'm going to be a nervous wreck now watching the babies I have left. Out of the 12 chicks I got with the ducks all are healthy save one that my hubby thinks drowned. Even though I had the marbles in. Wanted to watch the ducklings swim a little bit tonight but now I don't know if I should risk them getting a chill. Hubby feels horrible.
