I had eggs in the bator that day 21 was Tues. I had eggs under a broody to come off same day. No hatch. Thurs Morn I had a blue Orp hatch under her so I took three more eggs in the house and candled. Two nothing and one a chick still kicking. I have checked on these eggs twice a day cause it is so cold here right now a chick wouldn't last long if Mommie gets off nest. Well this morning another chick. A buff silkie. I guess the cold outside delayed development. I need to go get the rest of them today and candle to see if I need to toss. You can't count your chicks before they hatch but don't throw them out to quick either.
