Hi, we just brought 12 chicks home today. 10 are 3 days old, 2 of them are a week old. After putting them in the brooder, I noticed a couple of bloody poops, not a ton of blood, some pinkish red streaks. Although I watched them for a really long time, I'm not sure who made them. I did see one lay a poop which was mostly undigested starter feed, looked just like the food only a little wet. 2 of the chicks, are less active than the others, but not completely lethargic. All of them eat and drink. Any suggestions?
