I have an 8 month old hen that has been severly hurt by our roosters mounting her. They have raked down both her sides under her wings. I didn't notice it because her wings hide it and when her back feathers started falling out I examined her and found old wounds covered with thick black scabs. Some of her back is featherless and hard but intact. It's clean, no bugs or anything or green/yucky. She keeps worrying it and reopening it though so some is open wound now. I've been checking her every day since I noticed it Monday still the same really. She is still eating/drinking/laying/foraging free range on 10 acres, I give them snacks, she's still walking, using her wings etc. So a few days ago when I noticed it I let her be. Four days ago we got a white egg and I thought we had a new layer out of our new additions but realized it's her eggs changing from nice consistent large light cream colored to white, thin shelled. I can tell the difference from the eggs just last week to these new ones in feel alone. She's still laying white eggs and tonight I found one on the back porch stairs (extremely odd place for her to lay) and when I went to pick it up it melted in my hand. I wasn't too worried when she was still laying but now that her eggs are changing so dramatically I'm very worried she's infected or something. The two roosters will be gone by the weekend and we don't plan on getting any ever again this being our 5th attempt at having roos and having consistent problems. Oh, and she is having runnier poos but her vent and backside are clean. Is this just normal injury behaivor. In 8 months of owning chickens we haven't had any injuries at all except a roo getting killed by a neighbors dog and that was over within 2 hours of the attack so I'm unsure how to proceed. I considered bringing her inside but she's still so active and otherwise seems healthy I'm not sure what it would do for her.
