I have 2 pet ducks that have been mating but I didn't think any eggs were coming due to the season. Well I just found a nest with 15 eggs! Mama duck has not been seen sitting on them at all. I hurried and grabbed them because they felt cold and put them under a heat lamp. I left it for 5 minutes and noticed the temperature went up to 120 degrees! I'm worried if they weren't already dead, I may have killed them. Then I read that maybe she hasn't gotten broody yet and I should leave them alone. So I put them back in the nest. What should I do? I don't want them to die but I'm clueless! Help!
