Hen attacked in shock and broken leg ?

[Dublin chickens]

Hello all I found my hen earlier looked dead in the garden near my dog. I found it surprised it would be alive it’s not walking but is drinking water with electrolytes. I was looking for injuries and one leg seemed to not grab my finger as strong was rubbing up and down the leg and in the lower portion in one particular spot she seemed react to it. Any advice

Hard to know the damage but I would keep her warm, segregated and keep getting fluids, electrolytes and some food into her if poss. If the leg is truly broken then that could be tricky but they do seem to heal from sprains and other such injuries. Once she gets over the shock you might be able to gauge the damage better.
