Can anyone help? My hen just pooped this out?

It appears to be lash material. Did you pick it up to see it's texture? Was it kind of rubbery? Salpingitis is infection/inflammation of the oviduct. If treatment is started early enough then antibiotics might help. It's often advanced before it's known the bird has it, some birds never pass any of the material it just builds up inside. It can be very resistant to treatment, but no reason not to try.
