I have 2 turkeys. One has been fighting this sinus thing for a month or more. The other has not caught it, thank goodness. They are housed together in a pen. I ran them both through a 3 day cycle of Duramycin. No help at all. I have some Corid. I have not tried that yet. I wanted to get some advice first because we are planning on taking these 2 to the butcher for the holidays. This is the first time we have had turkeys so I'm no expert on this. What do I need to do? Do I just need to cull him and keep the other? Or is there something I can try to clear this up so that we can butcher him? I will not eat a sick bird.
