Hi! One of my 1.5 year old bovin brown hens is acting odd today. She looks like she is trying to trow up. Free ranging she looks and eats as normal but in coop run she is shying away from others (not as social). No one is picking on her and one of the 3 did not lay today and im assuming it's her. I picked her up and felt or crop...feals a bit full and mushy. I initially read online about helping them empty their crop, I tried for a couple of seconds tipping her down and massaging but only a bit of drool came out and i wasnt confident enough to try it again. I gave her olive oil instead and also noticed she has a patch of feathers missing on her checks with red skin. They are not molting and everyone else seems to be doing fine. Could be sour crop, or impacted crop or some kind of worm? Thanks for any advice.
