I had a white one (we think Chantecler) that I found in the brooder dead a week after hatch. No idea what happened. She wasn't sick, no signs of distress. I have no clue. It still puzzles me. So sorry to hear that you lost her.Woke up to find Minny ( our Serama - had died) I found her first before my daughter- thankfully- But I am so sad about this. I knew that they had a high chance of dying in the shell but I thought that once they hatched - they were good? She didn't seem sick...or overly weak. I just don't know what happened.
