I have just recently started having a problem with infected foot feather follicles (say that 3 times fast!). This includes a swollen thick red line up the feathered side of the leg. Then I noticed a non foot feathered bird with a very thin red line in the same area so now I’m thinking whatever causes the line is also causing the infected foot feather follicles rather than vice versa.
I quoted myself to explain what’s happening. Please read and advise if you can.
