Hello - I'm trying to see if anyone may know what's going on with my roo's comb. I noticed the back end was a little dark the other day, and it hasn't gone away yet. It gets like that in winter sometimes when it's gets pretty cold [and I'm in San Antonio TX, so that's not saying much], but it always goes back to bright red once the temp gets back up. It's kind of like his own personal little thermometer, but I'm worried since it's still dark. Anyone have any ideas on what this could be? Is it possible he just hit his comb on something and it hasn't healed yet? Sorry the pictures aren't that clear - I only have a camera phone.
