Weird mass expelled?

[Marle94]

I’ve got two Seramas and two Golden Comets. They are all about two years old, and have been laying regularly all summer until recently. They are on 17% layer feed, with oyster shell available at all times and they get several hours of free range time daily.
The last couple weeks, I’ve been seeing a lot of soft shelled eggs and fairy eggs, maybe three soft shells each week and three fairy eggs total. A couple days ago, I got a tiny soft shelled egg, maybe the size of a jelly bean.
One of my Seramas is currently in broody Banty jail, so I know it’s not her.
Last night I went to close up the coop, and found. What I thought was another small soft shelled egg, but it was a mass of tissue, in a bed of liquid that looked like raw egg white, no shell in sight. It wa sort of acorn shaped, with a hole and a dark “rim” around the hole. When I cut it open, it was clearly not an egg.
I have no idea if I need to be worried, or what to do next, if anything.
(I tried to post this last night but I guess it didn’t go through)

It looks like a small bit of lash egg material which is a sign of salpingitis or inflammation of the oviduct. Do you think it could be from the other serama hen? If you can figure out which one it came from, you could try treating with an antibiotic such as enrofloxacin or amoxicillin. Enrofloxacin is a better choice and is easier to source at this time. The 10% solution dosage is 0.1 ml per kilogram (each 2.2 pounds) of weight twice a day for 5 days. Jedds.com is a good place to find it. There should be at least a month egg withdrawal time, and it is not approved for chickens in the US, just so you know. Here is are 2 good articles on salpingitis:

The other Serama has been sort of MIA since last weekend. Saturday night she didn’t go in the coop for the night and wasn’t seen for two days. Then she made an appearance and vanished again. I caught her Wednesday and put her in broody jail.
