Blue Legs????

Today I found one of the Amberlink chicks lying on its side just inside the house.  thought she was dead, but obviously very weak, as she couldn't have been able to reach the food and water.

I brought her indoors and fed her on a drop of water in which I'd dissolved a little bit of salt and sugar and stirred in some plain greek yoghurt, which is all I had.  Fed her with a dropper several times, and tonight she was standing up eating like there's no tomorrow.

In the meantime, Brian brought one in, and she is quite small compared to the others, but she is covered in what looks like sores, but Brian said its where she's been pecked, and it looks like it may have got infected.  But what drew her to Brian's attention is that she is so tiny and her legs are blue!  Looks like she's cold.  Then we went into the big run and we've noticed about 6 others, all have these blue legs, but they are running around and eating and drinking okay.  The legs feel cold to the touch, but then none of their legs feel very warm, and Amberlinks usually have very pale pinky legs

does anyone hve any idea of what's the matter?  I'm looking on the internet too, but can't see anything related.  Thanks in advance.

Thanks Kate, don't think they have any breathing problems, its really weird, they are running around, eating and drinking, just these blue legs, as if they have a circulation problem.

I'll investigate Newcastle's later, but must go and clean them out now!

Is it anything like this?

If so it may be just a genetic variation rather than a disease.

I agree with Bodger.  Leg colour is due to pigment which is genetically determined.  I think there's a rogue cockerel in there some way back Grannie  

One of my mum's buff sussex has blue legs, whilst the other doesn't! Nothing wrong with her, just blue legs
