Started out with a still air little giant, temp 99.5 humidity we though was around 35-40 from day 1-18. Then tried raising it and the highest we could get to was 40. Now I am pretty darn sure the hydrometer is very drastically off. Anyways one chick hatched on day 19, one pipped at 19 and finally hatched today the 23 and then died a few hours later. The one that died was a huge chick, think week old size so I have no idea how it was crammed in a normal size egg. So now we have one active hyper little spash orp, he hatched on day 19. Then one little blue orp that pipped and hatched today in less then a few hours. The incubator stinks and I mean putrid smelling stink. Ive had two children of my own and had many horses and cats give birth around here, nothing ever smelled like that. I think the chick that die had something possible bacterially wrong because the whole incubator has reeked after it hatched. I didn't want to leave the little blue orp in the incubator to totally dry off because I was worried that if something bacterial had gotten the other that it would get it too. So I put little blue chick in a tupper ware in the brooder (so splash cant peck at the newborn) Little blue chick has a tiny pea size sack looking thing on his belly/bum, is that a not totally absorbed yolk that I should leave alone and hope it absorbs? Little blue chick was also screaming up a storm till I moved it into the brooder. Are the rest of the eggs most likely not going to hatch? its day 23, I see no pips and no movement at all. I know for next time I need to find a better hydrometer and make sure its accurate, but what else went wrong?
