I have a question about incubating my own eggs: This past weekend we culled one rooster, leaving us with 2 roosters and 12 hens. Before we culled him this past weekend, we had a fertility rate of 50%. I'm going to check again this weekend to see if there's any change in fertility now that we're down to 2 roosters. I'm hoping that culling him will increase our fertility rate because we have a better roostern ratio. But my question is, should I not plan on incubating until I get a 100% fertility rate?
