Permanently egg bound hen

Hi. I'm new to this forum and fairly new to chickens. I have 2 hens in my Eglu with a 3 metre run. I got a new hen 10 days ago (Brown Nick) she laid on the second day, which was a small egg. I would guess that she's 5 months old maybe. The problem is she is now always egg bound. I've read about the classic signs..... very lethargic, standing motionless, drooping body etc. When I first noticed this, I gave her a warm bath which produced a shell-less egg after about 20 minutes which I was very pleased with. Two days later, still no more eggs but same symptoms. At about 10pm she was standing in the run, and while standing she laid another shell-less egg. It cant be right that she's up walking around at that time of night? During the night last night she laid an egg with a shell in the run which is good, but she's in the same non mobile sleepy state today. She has, in the 10 days that I've had her, laid an egg in the nest box. I feed then layers pellets, very few kitchen scraps and water with an Oregano additive. Please can you help. It surely cant be right that this is going on. Many thanks. Andy

Hi Aunt Sally

Sorry for the late reply.

I followed your advice and it worked a treat. I gave her yogurt, cod liver oil and extra oyster shell. Within two days she was back to normal and now laying an egg a day.

Thanks for you advice.
