Currently I have a pair of d'uccles and a pair of silkies. I had 4 more girls but they died from markes, so this is where I'm at now. I'm going to add more girls very soon. Coop - 4x4 - they stayed in the coop for a long time straight when we had a lot of snow. Couple weeks ago, I started finding d'uccle roo tail feathers in the coop and within a few days he lost all tail feathers Silkie roo is younger but much bigger - possibly bullying? And lately, I've noticed that d'uccle roo doesn't crow. he used to be the prominent crower. I don't see any physical damage, other than the missing tail feathers. This morning it looked like when I threw scratch down that d'uccle was eating and silkie came near and I think d'uccle backed away. Could have been coincidence. I'm trying to watch them more when they are out. Opinions? I didn't intend on 2 roos, especially with only 2 girls but that's how it happened. I would have major trouble rehoming one because of mareks. thanks!
