I don't know what this is?

@CSAchook I'm sorry for your loss. Thank you for sharing this about Buttercup.

I have never seen that before either. But...I will play with a thought here. I could be wrong. Yes, I do agree it looks like big meat spot. I wonder if the contents is a cancerous ovum (egg yolk) that is being dropped and it's being laid. @casportpony had a hen with this cancer (Cystadenocarcinomas) I wonder if she ever had something like that in her eggs or could tell us what those ovum felt like?

I think you are very likely correct. I described it as like a meat spot because it was red and flashy in appearance, just like the OP’s picture. And I could not think of anything else to compare it to. It also had a sort of cord bit coming out of the end of the shell. Again, just like the OP’s picture. But what I neglected to mention was that the vet that looked at it thought it had some characteristics of an egg yolk, although she was not 100 percent certain. It was certainly a sign of a serious reproductive problem in Buttercup’s case. But she had a good life for the two years we had her.

I don't know if a cancerous ovum is "semi-solid" or not, that's why I asked Kathy to chime in to see if she had felt any of those. I do agree with you. Your photo and the OP's both look "meaty" or like a big meat spot. Her's somewhat reminds me of raw liver.

How many girls do you have? Is camping out to check each lay an option for you?
