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 back with great hatch rates. 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 protected] They will ship out the day after payment is received.
