I have a hen who has had what appears to be losing of some feathers on her upper chest for a few weeks now. And this morning I noticed she had a red spot on her chest. She has been acting/eating completely normal. There is also a red spot much lower on her belly. Being she's about 20 months old, I'm wondering if this may be molting? None of the other girls have this going on now and only 1 hen molted earlier this year. She didn't act like it was painful when I picked her up to take a look. I appreciate any thoughts.
