I've been hatching ducks for 2 years, and never experienced this kind of loss after the duck hatched. Out of 10 chicks that have hatched in the past week, 4 died after a couple days. They had dried off and seemed like they were doing well. They were all walking around and peeping. I check on them at least once an hour and every time they are doing well, then I come back and one is dead! I keep the brooder clean, with free water and food. (I don't think it's a bacteria as 6 are doing well). I have tried putting them on a blue blanket so that their food does not blend in, to encourage pecking and eating. I also added ground up boiled egg to the feed. I've also tried sugars water. I currently have a two day old chick - who is by himself in the brooder as he hatched several days after the other ones and I was worried he would get trampled - he does not want to eat or drink unless I have dipping his beak in the water! Help!
