I have 3 Dark Brahma pullets. 1 is 8 months and other 2 are about 7 months. The oldest is laying and the other 2 should start in the next month or two. I went out to check the girls and 1 is pecking at the air like she's eating but not getting even close to the feeder. She is thin compared to usual, and has some drool. She's walking around with the guidance of the other 2 girls. Yesterday she was fine, scratching around eating her feed, and nummies. She's usually very skittish but today I was able to just walk up to her and touch her. I tried to see if her pupils will contract but they are huge. She has almost no iris showing. Also her crop has nothing in it. I can usually get my hands on her once a week but not like I was able to today. I do observe my girls every day when I give them a bit of scratch. Her eyes were fine yesterday, she had a nice full crop, was eating and drinking no problem. What is going on, and how do I help her? I need to make sure the other 2 girls don't get sick too. I also want to help her because she's a real pretty sweetheart. Please help me help my Everest.
