Earlier I posted about a hen that's acting a bit off: https://www.backyardchickens.com/forum/viewtopic.php?id=259037 She's still acting strange. Won't eat. Did take a few bites of applesauce. She just had a runny, mustard colored stool that according to the chickenkeeper's guide to poo is either a cecal stool or worms. The flock was last wormed in November of 2008 with valbazen. I also have (generic) ivermectin pour on available. Should I worm her when she is definitely run down?
