About a wk ago we acquired 2 one month old poults. They seemed to be happy, playful, no real health problems. Monday I woke to one of them no longer alive in it's cage. We kept the two together in the same cage outside. It had gotten a little cool that night, 54*. There was no rhyme or reason to his death. The evening before he was up running around chirping his little heart out, then he was dead. I was curious if I should be worried about the other poult. Hadn't really noticed him acting sickly but his stool has been a little runny today. Also we've been feeding them Manna Pro Gamebird food since it was labeled on the back as a starter/grower. I didn't know if this may have had anything to do with it as some ppl feed chick starter til they get a little bigger. Any advice is much appreciated.
