RIP my little beauty

Nasty surprise for me today. My best chick from my best pair DEAD at 35 days old. She was very thin and had an empty crop. I totally blame myself for not being thorough enough with making sure chicks have full crops. My guess is she starved to death. Being at weaning age, she should have begun to feed herself. Foster dad is wonderful at feeding chicks and the three remaining chicks are chubby . This has never happened to me before. Lesson learned.  RIP my beautiful.
