Agh. Let chickens out, Ms. Broody (Past Tense) was attacked again by other chickens, esp. a Bantam-Easter-Egger hybrid hen. Does she sense the other hen’s weakened condition (from brooding?) Relocated Ms. Broody PT inside fenced area for now, will try again tonight. I don’t think B-E-E ever went “upstairs” to roost with B(PT). Have not had such problems in the past - hate to sacrifice any hen to the pot, but B-E-E may have to go. B(PT) is a better layer and much tamer.
“was then attacked”. Ok while penned up in a group.
If you have a cat carrier or other small cage, I’d suggest using that to reintegrate the hen. Keep her in the cage with her own food and water, but set it in the hutch with the rest of the chickens. It usually takes about 3 days of that for my flock to accept someone, even if it’s one of their own.
