Is this a lash egg? If so, what do I do?

[Perris]

further to the last, this is what lash material looks like

(two lumps of it intact and one cut in half)

x2 on what Perris said, I can't tell if it's a lash egg. We'd need to see what's inside to determine for sure (as well as the smaller lumps that appear to be attached to the lower parts of the image). The largest mass appears to be a shellless membrane but the smaller bits could be lash material.

IF it is a lash egg, even after determining which bird it is, you really won't know if the antibiotics worked other than not seeing more lash eggs and/or the hen degrading in health. Salpingitis can be bacterial or viral, so antibiotics may or may not help depending on the cause.
