I have a 5 month old HiLine - she has had a swollen crop on one side for about 2 months. Bridget seems healthy, has shiny feathers and seems to be eating drinking and pooping ok. She is smaller in size and her comb has not fully developed compared to our other chicken and has not started laying yet. I have tried massaging her crop and she vomits up bile like fluid. Today she puked up bits of grass then the vomit smelt foul but the swelling has not gone down. Knowing nothing much about chickens can someone give me some advice please? Is this normal? I'm a bit afraid how far and how much I should massage her crop - am I hurting her?
