Hen with bound egg symptoms but no egg

[Wyorp Rock]

Sometimes posting a video with a link for us to watch on YouTube can help us see what you see. Mareks can happen at any time, but is more common during the first 6 months, unless a new carrier chicken has been added to the flock. Of course, wild birds can also carry it. Vitamin deficiencies can sometimes affect the legs, but the reproductive disorders that Wyorp posted are also a cause of lameness. If your hen should die while you are gone, I would have the person watching your chickens place the body in a plastic garbage bag in the refrigerator (not freezer) in case you want to have her tested for Mareks by your state vet. Hopefully, she will soon get back on her feet with vitamins and nutrition.

I agree, a video would be helpful. As always @Eggcessive has given helpful advice. You can try giving her some poultry vitamins (with B2-Riboflavin), that may help with the legs issues.
