Hi all, 5 days ago I hatched 3 silver appleyard ducklings. All was going really well, all 3 were strong, lively, eating and drinking fine. This morning I woke to a power cut but don't think that is the problem. One of the ducklings is chirping constantly and cowering in the corner. I've picked him up and placed in my lap and he settles straight away, however, when I put him back in the brooder he immediately goes into the corner with his beak down and starts chirping again. The other two are fine and normal and I have not treated them different so the sudden change in behaviour is really concerning. I am feeding them non medicated chick starter with niacin and have had the little one drink a bit of water with electrolytes. I haven't managed to get him to eat anything although the last few days he's been eating great! I'm so worried, does anyone have any ideas as to what may be happening?
