Hi, please help as I am not sure what to do. I have three chickens, two silkies and one (i think) is a Isa Brown. The Isa Brown usually follows me around the backyard and digs in when they get any food treats. Yesterday I noticed she isn't following me around and will often just stand or sit. Her tail is still up and so are her wings, but she has been pooing greeny yellow/white stuff. About two days ago we gave them some pasta in sauce (she was fine then), I'm not sure if this made her unwell? Please help as any advice is helpful!
