I'm a little concerned about both of my roosters this winter. One is SC and the other is RC, but both combs are huge. I am seeing some purple in parts of their combs that makes me think that they aren't getting very good circulation. If this is going on during the warmer months, I shudder to think what I'm going to see when it gets cold! I'm hoping that part of the problem lies with them being caged a lot, so they're not out chasing the ladies 24/7 and getting exercise.
