It's only day 5 for mine and I'm seeing really good veining in over half of them. I was suprised to see anything, and all I did was run the candler across the tops of them. My pastels haven't been fertile yet, but some of these are fertile! I finally have fertility!
I have 2 hens and 1 drake in a pen. I see him court and mate one of the hens, but not the other. Her eggs have not been fertile for sure. There is no interest from either the drake or the hen. It could be both of your drakes are mating, or just one. I'd imagine if they aren't fighting, all is good?
I use the 2:1 ratio. At his age, he may not be able to cover that many hens.
You are dealing with the B/B/S gene, (blue, black, splash) In the blues you are going to get a percentage of blacks, blues and splash....not all blue. It sounds like you have a black, blue and splash in your batch. Metzer Waterfowl calls the splash "silver" in the Runners, I noticed.....I love the B/B/S Runners, and was thinking of getting some eggs.
ETA: very cute baby, by the way....
