Hello everyone. I just got back from a week of onsite and I need some help. I have a marans hen that comb is very pale (almost white) and is not laying. It has been at least 4 weeks. We sepeated her last week and tried sulfed in case she had cocci. I was going to try and give her some general antibiotics ( tylan) by injection to see if it would help but mario found a soft mass in her Lower abdomen. I have been afraid she has something internal

. She had low energy but was OK until last week but she is going downhill. Mario tried putting her outside yesterday to some sun but she was litliss and getting picked on.
She is walking OK ( no penguins) and the mass does not seem egg like. Plus if she had been egg bound for more then a month I would have a dead hen no?
Any advice? Her poop looks OK and she had been wormed recently. I'm wondering if I should just give her a companion and let her go gently or if there is something to try.....
