Your doing better on your duck math than me. I only wanted 10-16 this year max. But my first hatch of welsh Harlequin was looking like nearly all males. 4 females 7 males, so to fix my ratio I started more eggs and ended up ordering 4 females. My friend the ducky enabler she is kept giving me more eggs. Which I had to try and hatch because they have the blue egg layer gene really strong in their flock. And well I want a Cayuga that lays blue eggs!
Now I am up to 26 ducklings. And I want to incubate more eggs still. I have 3 eBay ads I am watching for the last breed I might add. But I really shouldn’t. I already have 10 more ducks than planned and I still don’t know if they are male or female for sure on some!
