So, last night i go out to the coop to lock up for the night. I find 4 of my 7 girls on the roost, one by the door to the run (that's normal, she's always there) and one is on top of their waterer, and the other is in the window! So, I got the one off the window and picked her up to put her on the roost. I look at the chicken in my hands and a brownish liquid is flowing out of her mouth. It was coming out for like 3 seconds but it scared me! What could this be? It was just flowing not projectile or dripping or anything. I just got them 2 days ago, could it be stress, or that she changed foods? I know that's the case with dogs or cats if you change their food too fast, but does this happen with chickens too? I'm worried about my little Flash. Does anyone have knowledge or experience with this?
