We just started raising chickens (we live in Puerto Rico) and in this week, we've found 8 peeps dead. They seem to be all dying in a similar way and I'm not sure if fire ants or perhaps centipede bits? Does anyone have any info on this? They seem to stop walking or are at least slow and within 5 hours they seem to be gasping for air, with a limp neck for an hour or so more. Maybe it's a disease/infection/parasite?
