Blood in eggs and other crazy eggs, help!

[Rozzychick]

My 2 year old Lace Wyandotte didn't really start up laying with the rest this spring. She is a nervous bird, would often just lay her eggs on the coop floor. Fast Then she had a dust up with a hawk where she lost a few feathers.
Then she laid a fairy egg with no yolk. A couple weeks later and it's just gotten stranger. I'll attach the photos below. But several times have found what looks like bloody tissue (not actual liquid blood) in albumen with no sign of shell on the floor of coop. She also laid a membrane egg that looked to be full of blood and albumen. Then one while a shell but also a tail! Then a soft one with tail and blood spot. Today just a chunk of bloody issue on the coop floor. I have been checking her vent, it looks fine. I just finished a 5 day corse of Enrofloxacin and a couple of day with 1cc of Poultry Cell and calcium supplement right down her beak. Now giving her a couple day of probiotics in the water.
My biggest worry is disease. She has good comb and wattle color and appetite and poops are normal. Could this just be birth defect?

It sounds like she is having some major problem going on with her shell gland or oviduct issue. I had a chicken who laid a bloody egg occasionally, then every time, and then eventually, stopped laying permanently around the age of 2-2 1/2 years. Has your flock ever had a respiratory illness, such as infectious bronchitis? Here is some reading about egg issues:

Thanks for your reply! I have the Chicken health handbook and I agree. We have never had respiratory illness that I know of. Your story gives me hope that she'll pull through. I don't mind if she never lays again. I've already given her a course of not food safe antibiotics meant for pet pigeons. It seems to maybe have helped in that all that discharge could have caused an infection. It's now 3/30 Her poop looks good, it had been suspiciously black like she may have had internal bleeding. Her comb, energy and appetite all good. She is a rescue who has survived a raccoon and hawk attack so I just want her to live happily for a while.
