up until this batch i have only ever hatched ducks, so tell me if this is just a chicken thing! i candled last night, day 8. i have 8 bcm's that i am not counting in the mix because i can hardly see a thing in there. but anyways out of the rest of my eggs only 12 out of 26 have veining. of course, i will give them another week before i candle again, but still it seems like alot of clears to me. when i do ducks, i very rarely have one clear out of the whole bunch. is this normal? should i contact the sellers about it? or wait until after the next candling? temp and humidity have been right on with no problems so far.
