On August 27, I put six duck eggs under a broody hen. She sat on them diligently and then two days ago kicked four of the eggs out of the nest. I held them up to a flashlight and three of them were black inside and had one end that the light shined through. They were obviously rotten. The fourth one was more clear, the light could shine through it and I could see a small dark area. Yesterday, she kicked another one out and the sixth egg had disappeared. The fifth one was also clear, but got dark after a while. Not sure what's going on. I'm fairly certain I have a drake, his quack is definitely a boy rasp compared to the females' squawking. I checked some eggs I cracked open to see if there was a halo, but it wasn't blantantly obvious like my chicken eggs. I've never seen the ducks mate. I'd really like to get some eggs to hatch, but maybe my drake is shooting blanks.... or isn't interested in the girls.... Any thoughts, suggestions, tips???
