Chicken acting weird

[chickenlady02]

Hey guys,
My Isla brown has been laying fart eggs. Really tiny eggs with no yolk. Today she started laying egg whites with no yolk and no shell. She is literally just pooping it out. She is not very well. This is the most energetic chicken ever, all day she has been sleeping out in the garden. I've had her for 3 years and she has NEVER slept in the garden. She has been turning down her favourite food (sunflower seeds) we tried to give her some and she turned them down. She has been walking really sluggishly and we r getting really worried. She is only 3 years old.

Here are a couple of her latest poos. Please we would really like some help with this
Thanks

Can you cut open the white thing she laid to see if it looks different inside? I would wonder if she is not laying internally or have salpingitis. These problems alond with egg yolk peritonitis are very common in today's hens. If you are a fan of antibiotics, you could try some from your vets. They sometimes can help early on, but there is no cure to these diseases. Here is some reading for you:
