in the 25th and 26th I got three chicks. Two black ones were hatched the first day, and a brown one the next. The brown one, Brownies, seems to be less vigorous than the two black. She always wants to be under mama and she doesn’t run around. I put poultry nutridrench, apple cider vinegar, and chick probiotics in her water. I’m hoping that will help. Is this sickness, weakness, or just later development? I’m hoping so hard she makes it. She is adorable and super sweet. Anything else I can do?
