Dying baby ducks days after hatching!

[Macie2003]

Hello everyone! I am posting this thread because my flock of 16 duck eggs hatched but I have had 5 drop dead every day after seemingly acting normal. I only have 5 left now and I don’t know why they are dying! I moved them from indoors to outdoors after 2 days after hatching. I gave them electrolytes and vitamins in their water everyday but it has been in the 90s everyday and they haven’t needed a heat lamp. I don’t know if they are overheating or what but they have had ample water every single day. I put a brooder bantam hen in with them and she didn’t reject the ducks and took them in. I have been giving them unmedicated duck chick food because my grandpa told me it was better for them. I have now given them some medicated food for tonight. The brooder momma was letting them crawl under and over her. Please let me know I don’t want the others to die.
