Too Much Moaning

Ally (or is it Pally?) has taken to moaning. Moaning. Truly. A most horrible sound rather reminiscent of an over-tired small toddler. TB and Myself listened for a long (too long) time yesterday. Doesn't seem to be anything amiss with the chicken - It just moans, eats a bit, moans again, has a dust bath and moans periodically during that too. TB looked rather sweet as it squatted in front of the pen, tilting its head from one side to the other.
