i used to give them starter but i switched to flock raiser. the label says it's also for day olds. is that a good diet?Chicks do better being hatched as day olds. Your chicks look like they could be around 5 days old. When you ship chicks that have had food and water, and they are that young, they don't ship well. If they were day olds, mailed out right away, they would not have feathers like those.
With that being said, they look like they could of been on a really high protein diet. Some people give there chicks game bird starter, they get pasty but really bad. They tend to be lethargic, and when they do move it looks really weird. They have there head really close to there body, and there head is tilted back a little bit. They usually die from anorexia. When the primaries are dragging like that, I usually count that as a weak chick. I will mark it, and usually not keep it. I also want to watch it grow and take notes. If the feathers "fix" themselves, I might keep it..............IDK, you can't keep them all! So you got to figure out what you cull method is going to be.
