OK...I'm about to give up. I've had about 8 mottled bantam cochin eggs...maybe more...I've lost count...and I haven't been able to hatch any of them. They usually quit sometime between day 5 and day 16 or so. I've gotten them from 3 different breeders so I don't think inbreeding is the issue. Is this a particularly difficult color of cochin to hatch? I have 2 gorgeous roos and 1 hen and would like to increase my flock. So far...no luck. I've also had some difficulty with white. I've only been able to hatch one white so far. I do have one in the bator that is ok...so far...at day 9. I can hatch gold laced, blues, black, frizzles, reds, buffs, silver penciled, etc...but NOT MOTTLED. Help!!
