this is what we are trying to tell you, Ours died in the first few days of being WEAK your first batch sounds like ours, Look at what you posted , you say at 2 weeks old they are getting SICK , gasping for air and pooping green, That is not what has happened to our chicks. our we lost in the first few days from being weak on arrival. Not once has anyone else said at 2 weeks they got sick with green poop and gasping for air then dying . Sorry but it really sounds like they caught something and I would think if it was from ideal we all would have the same thing happen which we have not.Is anyone else having a problem with failure to thrive babies from ideal??? I was having great luck with Ideal birds and it all went down-hill! My last order was 30 rare breed pullet specials! Within 4 days I had lost 19 birds! They sent the replacements! They are 2 weeks old now and I have lost one every day for the last 4 days! Seems odd at 2 weeks old! The ones that die are very thin like they are not eating! The others in the shipment have doubled in size but they have not! Right at the end they are weak, closed eyes, gasping for air and pooping green! Minutes later they are dead! I know it's not me or my brooders because I hatch 12-14 of my own eggs every week and now have about 80 of them! None ever die after hatch! NOT ONE! The only babies that ever die are from these last 2 batches from Ideal! AM I THE ONLY ONE????????? this is w
