I am so sorry no one saw your post sooner.
How is your hen doing?
If a vet is an option, that is my first choice. If not, people have successfully treated breaks at home.
First, with any break, the chances of the bone throwing a blood clot are high. Start the chicken on some aspirin (1 mg per pound of body weight, but you can round up as a little extra won't hurt). Aspirin is a safe pain reliever for poultry and a blood thinner.
If it was an open fracture, the chances of infections setting in are quite high. The chicken would need to be on antibiotics stat. You can order an antibiotic called
Baytril 2.5% (
Enrofloxacin) online without a prescription. It is
squirted into the chicken’s mouth directly. The recommended dosage is 10-15 milligrams per kilogram of bodyweight. You can also use
Baytril 10% administered in the drinking water (3 milliliters per 8 ounces of water), but this is a less effective means of administration. If antibiotics are necessary, make sure you are providing
fermented feed or
probiotics in the water to ensure the chicken’s gut bacteria is not disrupted. A disruption in gut bacteria can cause diarrhea which is not conducive to effective healing. It isn’t a bad idea to provide fermented feed even to healthy chickens!
If you're able to set the bone, that is ideal. If the break is at the knee joint, I am afraid joints are much harder to set correctly. Here is some great info about treating, setting, and splinting a broken leg:

If you splint the leg, I highly recommending using a chicken sling for 4-8 hours a day to allow the chicken to be in a more natural position and keep the chicken more stable. It's easier and safer for them to eat and drink when standing as well.

Ultimately, there is always a chance that amputation is the outcome. The link I provided discusses amputation as well. A chicken can certainly live with one leg.
Finally, there is always the option to euthanize. No one would judge you for making that difficult decision.
I wish you the best of luck. Was this information helpful to you?
