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.
Or in an emergency - ie looks on its last legs - hold it upside down by
its feet. It will flap a lot and should release whatever is in its
crop.

We've seen - I mean felt - golfball-sized smooth
"plastercine" lumps in the crop. I know their
throats are bigger than you think, but even so ... !

This occurred after eating too many sprout leaves
and too much grass.
