We do have older ones and they didn't come from Tractor Supply. Our first batch of 8 we got last July at the 4h fair. They have been doing great. This was our 2nd batch we got in February, we got 2 silver wyandottes, and 2 barred rocks from TSC at the same time we got 2 Eggers and 2 marans from Family Farm and Home. They were just introduced to the 1st flock over the last month. We've had them in an extra large crate inside the coop and letting them out for periods of time throughout the day. This last week they've been integrated fully into the coop. Maybe she was being bullied away from the food and we didnt notice? There is still some bickering when we give snacks but no attacking that we've witnessed. The coop is 12x10 so plenty of room too. Or maybe our first batch from the fair has a carrier that's not showing symptoms? But I'm really just hoping this settles as it's not getting worse. We have our first coop which is 4x6 that we have her in right now, I put a puppy playpen around it so she could get outside but not get too far being wobbly. She ended up jumping the playpen and back in the big coop when we went to put them away last night. That's a huge improvement.
