I had my doubts about the eggs I set on Easter Sunday, but I finally saw veins on 3 of the eggs tonight. Woo hoo! Now I can quit messing with them for a whole week! I'm thinking 2 of my 9 aren't fertile. They are blue cochin or blue cochin/favorelle crosses I'm told. Do cochins usually take a bit longer to develop good veins? With my polish I could always see great veins by day 3! Maybe it's just the brown egg color. They are kind of porous, and were a bit soiled when I got them. I hope I didn't ruin them by wiping off the yucky stuff with a damp cloth, but I couldn't bear to put them in the incubator the way they were. Any tips for hatching cochin eggs aside from the usual?
