New here- bear with me. I have 11 girls who are 11 weeks old. All but one are thriving. 5 weeks ago we moved them outside and everyone was doing very well until 3 days ago. One girl seems to be sick. She is our smallest one. She has been laying down more, and today spent the day in the coop alone. I did not see her eat today or yesterday. Her poop was watery earlier today but seems to have returned to normal. She looks fine as far as feathers and breathing. Any input would help me. These are our first ones and I really want to succeed.
