I have a two year old RIR who is incredibly sweet. It is coming straight out of her vent and looks like a semi-clear tube almost. It is probably a centimeter in diameter, membrane-like, and maybe filled with liquid. it is several inches long (4?), but kind of looped over itself. I guess about a month ago she started having symptoms of egg drop syndrome (thin, sandpapery shelled eggs), but I just thought it was a calcium deficiency and made sure she had more access to oyster shell (I hadn't been doing that before b/c had never had a problem and didn't know I should). It didn't help and I started doing research to see what else it could be--I was really just thinking mineral deficiency at that point. That is when I came across info on Egg Drop Syndrome. I don't know that she has all the symptoms, and I really have no idea how she could have become infected (we added two chickens from a friend 6 months ago, but they never showed any signs of problems and prior to that no chickens were added since last spring, all of which are still healthy). A few days ago she started acting lethargic. I now have her separated from the flock and started antibiotics (terramycin) for both her and the rest of the flock (I lost several guineas to a virus a couple years ago and I really don't want to go through that again). I feed a layer pellet, oyster shell supplement, and they freerange all day (not at night b/c we have lost several to foxes, so they are in Ft Knox after dark lol). I provide fresh water but I am sure they also drink out of a small seasonal pond on the property. I think that might be all the info I have. Does anyone know ANYTHING about this?? Like I said, this chicken is incredibly sweet (will jump up in the car with us and has even let my 4 year old daughter carry her around before). Our chickens are not pets, but this one is so friendly that we can't help but be attached to her.
