Yeah the sprig thing is bugging me too....I thought I had gotten rid of all the hens with sprigs, but found one this week with one. I'm wondering if she didn't just wander back down from the other pen at the house. Anyway,,,I remember back,,,a WHILE back the conversation turned to sprigs and how to find out which hens/roosters were carrying them, but I'm old and forgot everything. So now I gotta go back through the thread to find it. Was also thinking, if the people I got them from only culled sprigged combs out, but didn't find out which ones are carriers, then those birds are still in their flock, and every bird I've got could be a carrier....so I am bummmmmmed
Luckily,,,,,there were absolutely NO carnation combs in any of the birds, so I know that's one less problem. OK,,,I'm done venting
