Not right off hand but I'm sure I can dig you up some off the web.
Leg colors vary from breed to breed and chicken to chicken. When I talk of pale legs on the other thread, it's because I know these birds like the back of my hand and I know what color their legs are at what time of year. When I say they are pale, it's really in comparison to their norm. Each flock and flock member has a normal leg color that is specific to them, some breeds have a specific leg color that identifies them as to the breed, etc.
When a chicken is limping, it's best to identify that particular chicken and examine their feet. There are a few things that can cause a chicken to limp, but you'll never really know what it is unless you first look at the foot. If you have examined the whole foot and could find no outward appearance of any abnormality, no calloused or scabbed areas, no redness or uplifted scales, no broken nails, no joint deformity, no broken toes, etc.,~ then it's time to determine if this is a chicken problem or a flock problem.
A chicken can sprain a leg/foot just by jumping down off the roost or getting it caught under a feeder or in wire and it may never show on the foot itself...they just start limping. This should go away within a few days. If it doesn't then you need to determine if this bird can still thrive with this disability.
If you have more than one chicken limping, it's a good bet that you may have a flock problem vs. a chicken problem. And those problems can be myriad and varied in nature when trying to determine what they have, why they have it and what needs to be adjusted to get rid of it or prevent it from happening.
Too much info for just one post or thread, really. That kind of info is accumulative in nature and comes from reading, reading, reading, comparing systems and methods, what other flocks have or do not have compared to yours and why, what you can change to make sure your flocks stop having or won't get such and such symptoms. It could be dietary, environmental, genetics, etc.
I'm sorry if that wasn't very helpful but it really is a process, this chicken thing, and we all have to go through it over time and one cannot learn it quickly....we have been at it for years and are STILL learning as we go along.
I have a serious belief that it is environmental. When I bought my farm 3 years ago, I was, and still am I guess, a city slicker acting like a farmer. I only have 4 acres, but there is a lot of work that has been done and still needs to be done.
Y'all can say what you want, I can take it and like to think I know my weaknesses and actually enjoy the bluntness of country folks.
Having a car lot, rental properties, educating myself to become an auctioneer, raising 6 teenagers, raising chickens and hogs with no experience, competitively fishing.... I keep busy...
Listen to me making up all of these excuses about why I haven't completed the work
Anyhow when I bought the place, it had been a showplace at one time, but had many years of neglect. I have only lived here full time for about 1 year. Out around the barn was completely overrun by multiflora and other prickly weedy viny plants. I have wandered back there and found 55 gallon drums, buckets of tar, cans, broken glass, fencing, tin, baling wire, the works.
Just 2 months ago I released a dozen or so feeder pigs back there and they have cleared it an shown me another mess to clean up. I have literally moved dump truck loads of scrap, trash and myriad other items including a torn down house that was in the barn away.
That said, in time, I will have it back to where it should be, but in the meantime my animals are suffering the found dangers and the slowness of their master to clean it up. Alternatively, I could keep them penned, but... I value their freedom.
Anyhow, thanks for letting me vent.
