Advice needed please - purple comb

I would think that there are three options here.

1. She has worms...solution..worm her.

2. It's the time of year. The equivalent of cold hands. Chickens display their circulation in their combs, whereas we get white or even blue fingers from cold, chickens can get lightly purple combs on the pointy tips.

3. Her heart is beginning to fail. She is probably well over 3 years old and combined with a tough start in life and her breed she is probably getting to be quite an old girl.

Best wishes. OL

Hi there and thanks to you both.

I've spent time with her this morning, no worms in her poo, they were all treated last month.  The temperature has dropped but we have had really good weather for the last few days and we live in on a plateau in a cutting on a steep hillside so are very sheltered. 

So unfortunately it would seem that she is showing signs of old age   Will will keep an eye on her to make sure she is eating and drinking and see what the next few days bring.

Thanks again
Kathie
