I have chicks that are in the coop outside and I have six that are in a coop inside my house. Yesterday my 5 yr old son was looking at all the chicks. He said mommy this baby is sad. He doesn't feel good. So we took him inside to be w the other chicks. He seemed ok at the time. Just now I went to look in on him and he is sitting down eyes closed. I picked him up after he wouldn't wake up. He is about three months old. He is v skinny. So I did look at his vent and there was some dirty spots from poop. His tummy is also bloated right wer his vent is. I cleaned it off. And kinda pushed upwards on his belly towards his vent. And this yellow stuff came out. I guess his poop. I didn't push hard. Just softly. I tried to give him water and food he just sits there eyes closed softly breathing. Someone please help with advice before he dies
