Purple leg?

 
I'm new to this so hope I do it right...
I need any advice on purple leg on one of my Rhode Island reds...
First I thought she may have twisted it & it was bruised, but over the last few days its spreading down to her toes?
Both my hens don't seem to be putting on any weight either..
Had them about 8 weeks...
Any help would be greatly appreciated..

I got them as point of lay, & had them about 2 months now
They both eat well, never stop...
Just the purple leg that's worrying me...
They get pellets & numerous other foods throughout the day, then mixed corn late afternoon..
They both lay every day, so no problems there, they eat a lot of grass & grubs..
never notice them eating the pellets, but they do in there own time..

I agree with jhub.

I don't think they will be underweight from what you have said about them

let us know how she goes could you put a pic on of her leg im v curious about it now

Hi Shellzy, how did you get on with your hen and her purple leg.  I have been watching with interest to hear what it is.  Hope she is ok.
