It sounds like she's laying internally. I have a hen doing the same thing. Internal laying could cause infection sometimes, so just have some antibiotics in hand. Once you see that she's sick, you can treat her to control the infection. My hen has infection problems form internal laying once or twice a year, and she's fine other time. I use Baytril and it works really good.Just want to give another update since it's been a few weeks since the last one. She is still doing really good, no signs of being weak/sick, and is back to herself. She is finally back to chatting with me everytime she sees me, and following me around.
The only thing I'm concerned about at this point, and I'm not sure if I should be concerned because she has absolutely no symptoms. For the past 2 weeks or so, like clockwork, every morning almost immediately after they are let out of the coop, she will go set on the nest, on average 30-45 minutes, every single day and she has not skipped a day, but when she gets off of the nest, there is no egg.
I'm not sure if she does it because she feels like she needs to lay an egg, or if she knows that's what she is supposed to be doing. When she got sick, she was still a new egg layer and had only been laying for a couple weeks or so. When she got sick she had stopped laying.
I'm not so much concerned about getting eggs from her, more concerned about if there is another issue or if she might hurt herself trying to lay an egg. At the same time, I'm trying not to worry to much since she has absolutely no signs that anything is or could be wrong.
