Hello, I didn't find a post on this one. One of my 6 mo old production red hens has swollen legs. Also, her comb is not dark pink like her sister's, it is very pale pink. This little hen is a loner in her flock of 8 assorted hens. She just started laying two weeks ago, and lays one little egg each morning. Is there something I should be worried about? She walks and stands just fine, yet she reminds me of a very old woman with very swollen legs.
