Well, my duck still laying so with the bator full, no need to keep them. I have 7 girls with 3 boys and they are very active.... I have had great fertility rates as well and those who have bought from me have replied bck with great hatch rates. I just hatched out 13 from 15 eggs. They all carry the crested gene but can not guarantee you will get a crested chick. The box will be marked fragile hatching eggs as well. The first picture is one that I received of babies that were hatched from my eggs. Paypal email@example.com They will ship out the day after payment is received. I would like to ship on Tuesday.
