Was her crop firm and full, or squishy this am? I suspect that she is having a reproductive disorder called salpingitis, and sometimes they can develop water belly or egg yolk peritonitis with that. That can lead to pressure slowing the crop emptying, feeling poorly, runny poops, and walking more like a duck. Offer some chilled coconut oil cut into small pieces (1-2 tsp daily) or some mineral oil or olive oil mixed into a small amount of egg. If her crop is puffy, do not massage it, but if it is firm, you can massage it several times a day to get things moving. Make sure that she is taking plenty of water. Let us know if the calcium helps, but she may be laying internally.
