The only fear there is them becoming crop bound
If that happens, we have found a useful technique
is to soak some bread in cooking oil, feed it to
the chicken, wait a couple of hours, then massage
the crop. After 2-3 days the mass in the crop will
be substantially smaller.

Similar technique as used for human constipation:-)
