Yes 8 is a good number for shipped eggs. BBS breeding can result in any of the 3 coloursK Riggs I haven't looked at mine they are in lock down. I was advised to put them in a bit early maybe that's why. Chicks go early to, maybe it just a guideline.
My little silkies are beautiful and fluffy now and 8 is a good hatch rate, especially from what I've heard about eggs being flown across the country.
Fancy you said blue and splash, I thought the blue was a splash too.
Blue, black or splash.
