I have one year old hen out of four that has very pale wattles and comb is starting as well. I'm thinking worms. Is that a good guess? It's been very hot and I have been away. They have been in great care but not by a chicken person so not sure when she started getting pale. Should I give her something else while I'm waiting for a wormer. Feel like she needs blood. Not thinking I'm up for transfusing a chicken. She is an EE. She is a great layer and was one in April.
