I have six one-month-old RIR chicks that are in a brooder in my house. They stay inside but do get some outside play time, and they have a diet of chick mash and grit, but I do give them broccoli as a treat mabye once to twice a week. Yesterday I noticed they were having diarrhea, it's watery and sometimes is brown, sometimes somewhat clear. They had broccoli the day before. Also, I've noticed they seem to be scratching their face, rubbing their beaks on their bedding. They aren't actually scratching themselves with their feet, just rubbing their faces/beaks. Is this normal? And should I worry about the diarrhea since they've been getting treats? Please adivse...thanks!
