one of (4) our 8wk, old pekins is acting listless, hardly walking around,and waddles funny tail feathers and breast stained, looks like had diarrhea. she is still eating and drinking. Got some "lifelites" and mixed some of that in all their water and made sure she/he (still can't tell sex of them yet) drank some. Thought should keep her seperated from the others...but they all got agitated so thought less stressful on everyone to keep them together and keep close watch. Read could be low on niacin, thats why the lifelites, but should I get something else...is this niacin from drugstore and if so...how much? Anyone else got idea what could be wrong with her. Checked feet and legs, they look ok and her eyes are clear.
