If she is having leg pain and no noticable wounds it can be many things.. a few things to try daily as my Female has been through this also..
First things first.. is your hen still eating and drinking? Having normal voids ( stools )?
Is she still laying eggs? If not when wad last egg laid?
Is she able to walk at all? Favoring a foot ( keeping off of it or keeping it lifted)?
If there are no wounds, have you tried filling fresh water bowls adding a half of a Multi B Vitiman to her water dish 2 times a day. ( for my Female we took half a vitiman added enough HOT water to a freshly cleaned dish. Enough eater to cover the vitiman, hot water will dissolve the vitiman very fast. ) then we full the rest of the water dish with cold water. She drinks it down with no problems.
My vet ( avain meaning birds/waterfowl) recommended this to us as the bird chick duck chicke exc may be low or have a vitiman deficiency.. Vitiman B's are common in birds..
Also to add honey mixed in every bowl of water, honey has sugar and sugar helps hydrate and boost energy levels..
Also the 3rd thing was to add nician to her food 2ce a day also. Walgreens and even
walmart carry this is a vitiman or a capsule form..
I got capsule form as it was all
Walmart had at the time I was there. We break the capsule open and sprinkle it over her food. Half a capsule each time. A bottle of capsules were around 7.00 at
Walmart over the counter
. And the max multi vitiman B was around 5.00 from
Walmart also. Honey depending on brand and size can range from 4 - 10 bucks..
We done this process morning and evening 2ce a day for our Female and she was well again in days..
Also were going through our Female moulting.. this has caused alot of weird behaviors in our Female.. vet recommended extra protiens during this time. As she is not laying eggs at the moment and wet or dry cat food, cooked hamburger, tuna as treats high in proteins to boost her back up..
Calcium also is a good idea to keep her eggs passing and healthy..
If you cant get your Hen to take pain meds, maybe try to hide it in her foods or if that fails try to disolve it then apply to foods..
Keep on it twice a day for a good week. Hopefully this helps..
Please keep us updated..
