I've noticed some runny poops lately (my chicks are 5 weeks old I believe) What does it mean?! Are theysick? Could it be the food? (They eat starter&grow from the feed store) I'm new to chickens so I have absolutely no clue. I've also noticed an occasional feather here and there, I've found 2 from the black autralorps and 1 from my red sex link, is this related to the runny poop? Normal?
