Poorly chicken

I quite thought I would be blipping about the sad demise of my poorly chicken today. Last night she couldn't make it up onto the perch so I put her in a little bed of straw, her comb was blue and she seemed to be fitting, but I tucked them all in for the night and whispered some words of encouragement, and locked the hen house door.
This morning I was amazed to see that she had perked up a little and her comb was less blue. This afternoon she is up on her feet again, she has staggered outside and her comb is red. Don't ask me why her tail goes down and not up as usual, I haven't a clue, but fingers crossed she'll be her old self again tomorrow.
