Blood in the egg usually indicates a blood vessel in reproductive tract ruptured. With this amount of blood, I would evaluate the diet of this hen. Get her on a good commercial layer feed and vary her diet with added greens and alternative protein sources such as insects or cooked meat.
You will see this in high production breeds whose reproductive tracts are under incredible strain to produce those big eggs.
The added tissue is a concern because it could indicate the beginning of an infection and the end of her laying career. Get your hands on you hens and evaluate their body condition. Occasionally, a high parasite load can case this, especially if the parasite is migrating through reproductive tract.
Since this is the first time, I'd improve the diet keeping in mind these super producers need a top quality diet. A fecal test will help determine what parasites you have and what to treat them with.
