Hi, does anyone happen to know why a young chicken (about 3+ months old) would be all fluffed up and lethargic? Her comb has lost color and is kind of scaly too. We put her on medicated chick feed yesterday but I don't know if that will help. She weighs less then a pound but looks like she should weigh at least 2 or three pounds. She's a barred rock. I am new to chickens and have taken a liking to this little bird. Don't want to lose her.
