I give up on shipped eggs. From now on I'm only going to hatch my own eggs or eggs close enough for me to pick them up myself. I've gone through 4 batches of eggs and only had one chick hatch and he died this morning. My temps and humidity have been perfect and I turned them and didn't candle much and eveything I'm supposed to and still no chicks! I realy think it's the X-rays the PO does that killed them. They either don't develope or they grow and have something wrong with them and don't hatch. the only reason this one hatched was because I helped and he lived 4 days and during that whole 4 days it seemed like he couldn't swallow right. So thats it! I quit on shipped eggs. I'm just going to wait for my girls to start laying or I'm going to find eggs with in 50 miles of where I live to hatch.
