I have a BCM rooster that is about 9 weeks old. He likes to eat non-food and eat feathers and dog hair etc. For the last week or two we have seen liquid come out of his mouth. My kids say he just "pukes" but I have only seen it happen when I pick him up (which we do gently) and then a teaspoon of liquid comes out of his mouth. He is otherwise completely well. He struts around and eats and drinks and poos just fine. I am new to chickens. Is this just a normal thing or something I should worry about. His sibling, hen, doesn't seem to do this at all. They are eating chick feed and free ranging a few hours a day and they get cement grade sand for grit plus whatever grit they find when they are foraging.
