Also, the loss of feathers could be just from the rooster breeding her.

Your roo could be ' over mating ' her. Roos , no matter what their size and stature , will often select a favorite hen or an easy target. Mites and lice are often difficult to detect and some birds are more affected than others. Check around her vent area and then about 2 inches above the vent, for egg casings along the feather shaft. Finally , check your feed bag and be sure that it contains methionine. Birds that are deficient in this amino acid will eat their own feathers and that of others in an attempt to satisfy their craving . http://msucares.com/poultry/feeds/poultry_feathering.htmlIf I could characterize the appearance of her poop as anything, it would be dark and sort of dry. I'm not sure if she's eating much, but she did appear to be looking for bugs this morning. Her eye is open this morning though she tends to blink it more often than the other and it has a sort of lazy look to it. Her vent appears to be clear. She last laid about 3 days ago and has been hit and miss for a while to which I attributed to what I thought was a soft moult. The eggs are lighter in appearance than her sister's and that's not usual either. I haven't seen any signs of mites or parasites on her saddle, but I did notice something this morning that somehow I missed before and that is a dark cast to her tail feathers. The other BO hen doesn't have this and I don't know much, but I would think if she had mites or other parasites, the others would have it too. The Silkie boys seem fine, full of beans and ornery as always. There is by the way only one Silkie roo in with the girls and he doesn't abuse them at all. I keep the others separate because they fight like crazy. Here is a picture of the feathers I mentioned with the other hen in the background for comparison.Here's a better shot of her saddle
