Our mommy hen hatched one little baby four days ago. She had systematically chucked all her eggs, but two, out. When this little one hatched, it was very weak and didn't seem to move around much. After three days we threw the unhatched egg out as she was favouring the egg and neglecting the baby. Baby was weak and not eating or drinking. Fed it a yolk and yoghurt mixture twice yesterday (Day 3 after hatching) and some water using a syringe. We were surprised at how Mom let us take the baby! This morning I fed baby again and it was starting to shuffle around. We had a beautiful sunny day and Mom took Baby out into their private little garden. They seemed to spend all day outside, Baby even started to peck at the sand. I realised the water was inside so Baby had not had access all morning since I had fed it. Brought the waterer over and Baby knew straight away to drink. I watched it carefully to make sure it didn't fall into the water. It drank quite a bit and then snuggled back under Mom's Wong. Half an hour later I went to check and Baby was lying limp in the soil. Mom left as soon as she saw us. Baby had water bubbles in nostril. Baby had passed away. We tried to open the beak which was also full of water. When Baby was tilted, water poured out the mouth. What happened???? Did it drink too much and choke? We have only had one other hen raise chicks before (they're now six weeks old) so this is very new territory!
