I have a few pens of chickens that have been having yellow droppings lately and have slacked off on egg production, otherwise they appear fine. totally alert and active and it's only some of the droppings that are yellow. There are normally colored droppings in there too. I treated them for worms today with piperazine water wormer. Has anyone else ever treated with that stuff? I was just wondering if that is a decent wormer. Also does anyone else think that there could be another culprit other than worms. I mean other than decreased laying, there are no signs of anything wrong. I also have some sulmet that I can give them if the yellow stools do not stop in the next couple of days. What do you guys think?
