I'm giving electrolytes now, thank you.I think the weird poop is the equivalent of meconium. Their bodies are clearing all of the junk out of their digestive tract that built up during their development. Once they start eating, the poo will become more normal. I give my chicks Poultry Nutri-Drench to get them off to a good start. For the first week or so, I alternate a bottle mixed with ND with a bottle of plain water.
May I ask how much you paid for shipping? I just bought some Jubilee Orpington eggs and the breeder charged 20 + and add'l 10.95 if I wanted the box to be labeled FRAGILE. I've not had any other breeders charge extra. I didn't pay it and WOW... the box wasn't marked this end up, live embryos or NOTHING. It was delivered on it's side in my mail box

Started the electrolytes and will give egg yolks in a few days. Thank you.I give electrolytes for the first 3-5 days. And then hard boiled egg yolk.
Mine was on the side too, even though it was clearly labeled!
May I ask how much you paid for shipping? See my note above to Amy.
