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 have 36 in the bator now and only 2 did not develop. 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.
