When our duck went for a bath tonight I went and had a look at her nest. She's been on the nest for 41 days now. I used a flashlight and saw that one egg is still moving inside. Another egg has pipped externally and is cheeping. However, I was horrified to see that small red ants were crawling out of the external pip hole. I think the ants were attracted because one of the eggs had exploded a few days ago. I immediately cleaned the entire duck house out, removed all of the nest material, sprayed Raid on the outside of the house only, and set ant bait traps underneath the house to attract any remaining ants. I got a lot of bites while I did this! I then added all new nesting material (torn up cardboard and goose feathers, similar to what she had before) and shooed her back into the house. She's in there now getting settled back in. Before I got her back in the house I watched the pipped egg for a while and I think all of the remaining ants have come out of the egg, and it's still making little peeping sounds. I'm terrified, though, that the ants are going to kill the duckling before it hatches. Any suggestions?
