We picked up 2 chicks from our local co-op, a buff Orpington and gold laced Wyandotte. Within 24hrs the Orpington died. A few days later we picked up 3 more chicks from the same place, 2 americanas and a Delaware. One Americana is now acting really weak. The other chicks are looking great. They peck a lot at the weak Americana. I have separated the chick so she gets some rest, but I'm afraid she is not doing well. She is moderately drinking tho so I am hopeful. Any advice? Is it me or just what may happen? This is the first time it has happened and we have had chicks before.
