Wow! @
hofhine68,
I absolutely love those pics and vids of your Niederrheiners and Bielefelders! The chick in the video is definitely a young rooster, or cockerel. Which chick is that in the pics? The one with the black dot or the light dot?
I've actually never seen a black fleck in our birds before so that's why I was eager to check it out. I feel this thread should be the center for posting pics and tracking which chicks turned out to be hens and which ones turned out to be roosters.
As far as Brinkhaven you mentioned 1/6 Bielefelders hatched and 2/3 Niederrheiners hatched. Well the Niederrheiner batch is considered "average" at 60% hatch rate and you have a 66% hatch rate. Something obviously went wrong with the Bielefelder batch, with a hatch rate of 17%. A number of things could have happened. Did you candle the eggs to see if they were fertile or not?
As far as hatching eggs, there are 3 terms to know:
1. yolkers
2. quitters
3. winners
Yolkers are eggs that were never fertile. Quitters are eggs that were fertile but for whatever reason the embryo / chick "quit." Winners reach the finish line and hatch out. I'd be very curious to know if you know any of that to help with my stats.
Generally, I've had good experiences and bad experiences with hatching eggs in general. I had 0 chicks hatch out of 14 eggs from one farm. I found out that 10 of them were yolkers and 4 became quitters. Infertility was the issue there.
