My 9 year old came in the house and asked me to keep an eye on her chicken today. She told me she looks paler than usual. I went and looked at her and is definitely not her usual self. We were not home for about 10 days and I think she has been acting off since we got home on Sunday. Her comb seems shriveled. She is usually the hyper one of the flock and now just hangs in the back. I let them out a bit to eat grass today and she was eating that but not with the ferocity that she usually does. Yesterday was the first time we got 4 eggs instead of 3 (no clue on which hen lays what when). We have had rainy conditions for 2/3 of the days we have been home and all 4 of them are covered in mud. Last week they had their first experience with very close to freezing temps overnight. She seems to be holding her wings fluffed out a bit but that might be my imagination. They are about 7 months old and I have never noticed them having problems with each other. Help??? I can't lose my 9 year olds baby.
