I have one with this problem too!!! I could never "fix" her. She still has a HUGE craw. However, her color is great and she is happy and laying!! I have thought about getting her a crop bra, but it is soooo hot, I haven't wanted to put anything on her. She is coping with her problem. Unfortunately, her name has changed from 'Tubby' to 'throwup chicken'....Yuck!! She is a Dom and very, very sweet. But, with her crop problem, she is slated for freezer heaven in a couple of months. (I hate that because the Doms are my special pets). She eats---alot--probabaly to make up for her crop issues, her feathers are beautiful and she maybe a little slower than the others, but she can sure keep up! So, best of luck...I hope your chickie gets better......
