We all think like that some times. Dont feel bad, its just being human really! Usually I find it all works for the best - this one might turn out to breed you some really fine babies. Im just a newbie breeding ducks but I can tell you in horses, plainer ones breed the real lookers, and the real lookers are hit and miss breeders.might not seem nice but i kinda wish this girl got hit with it instead of her sister. her sister was real pretty and would have likely produced real pretty ducklings, this girl might too but her crest is about 1/4 the size of her sisters and is on the side of her head instead of centered on the top back and her coloration is cream on white instead of fawny tan on creamy white. just hope that if the crest does get passed on its properly centered on any ducklings. could still get interesting colored offspring from her i guess since ive got a rouen and khaki campbell for drakes (other hen ducks left are a rouen, pekin, and magpie. not an ideal ratio but the rouen is the lead drake and the khaki is a wimp even with the girls).
Sounds like she's doing great, I wish you both the best of luck. I need to hear stories like this so I have hope to push on when bad things happen with mine.
