The first one at about 4 days old another 2 days later and one more today. They are in a brooder with shavings. Eating medicated chick start and ACV in thier water. They are in the garage under a light. 2 were silkies hatched here the one today was an Orp was shipped. They are all just over a week old now. The silkies were with the hens for a few days before being moved to the brooder with the Orps. Any ideas. Didn't notice anything wrong until they were just laying there.
