I have a red silkie that is 6 months old, she started just sitting...not participating with the flock, not scratching...just sitting. I removed her and put her in a crate for 24 hours to make sure she wasn't hurt in any way...Today when I put her with the flock again, she went off in a corner and sat....Is this Broody? I checked her and could not locate any injury or soreness...just seems to be "alone". Others aren't picking on her. She has layed and egg or two. 1. Is this broody? 2. How long should I keep her isolated.
