14 eggs. lost 5 in the first three weeks (got crushed by broody) 9 make it to day 21 (2 are duck eggs so we'll say 7 made it to then) is now day 24 no movement. thought id candle them while mama was off to stretch her legs. all 7 looked bad so i took them away (one actually exploded as i picked it up, i now stink to high heaven and cant get rid of the stench ) through them on the compost heap. they all cracked open and oozed out green stinky stuff bar two. looked a little closer...theres blood on two. look even closer, the membranes are moving theres chicks in there but a hell of a lot of blood. pick them up to take them indoors to try and salvage them...one egg breaks totally..chick slides out....havent got a hope in hells chance of saving that one now (but it didnt look like a chick that should be more than ready to hatch..looked about day 17/18? was more underdeveloped than the chick here...https://www.backyardchickens.com/forum/viewtopic.php?id=387061 2nd egg i have wrapped in a warm damp cloth on a heat mat but dont hold out any hop due to the amount of blood oozing out. what would cause eggs under a broody to be so far behind schedule???
