It's always difficult to tell from pictures but he red in the poo does look like blood rather than intestinal lining shed.
If she was my hen I would treat her for coccidiosis.
The dark green poo in the first set of pictures looks normal to me.
On a brighter note; I have a hen that walks backwards and cranes her neck in a similar fashion to what many might ascribe to wry neck. I've treated her with vitamin E plus plus B vitamins and it has made no difference. Apart form these occasional walking backwards bouts she is a fit and otherwise healthy hen. She lays eggs, has sat and hatched chicks and has no problems holding her position in the social hierarchy.
Also on a brighter note many chickens survive and can live normal lives despite having Mareks disease. Mareks is a but like the HIV virus in humans in that often the disease itself doesn't kill. Mareks will weaken the immune system and leave the chicken susceptible to falling ill with complaints that a chicken that doesn't carry the virus would easily recover from.
