I have a barred rock born in March. She is not laying yet but is squatting. She is in a mix of different aged chicks and hens. She's getting starter grower currently. Today I noticed when she went to eat she shook her head and food went flying as well as some clear mucus! In my hair and over the top of her head! Nasty! I tried to get her to eat some crumbles but she didn't seem interested. I also tried apple sauce. I then put a few drops of olive oil and ACV in her mouth. She left her mouth open, closed her eyes and sneezed again! clear mucus flung around again. She's now by herself with water and ACV, egg, applesauce and crumbles. Her crop feels like a deflated balloon with sand or gravel in it. I must add that their food bowl was empty this afternoon so not sure when it ran out! little pigs are getting big and I guess eating more than I realized! Any ideas???
