She is an ex batt we have had for 4-5 weeks. Yesterday afternoon we spotted she was looking unhappy, head scooched down into neck, drinking but not really eating, eyes looking a bit hooded. Comb has gone floppy.
Have squished her crop - soft. Checked vent - nothing dodgy. Squished her back, rear and underneath - no obvious hardness or lumps, but bit of a dirty bottom.
Could she be upset by us moving from crumb to pellet? what else is it likely to be?
