My Black Sex-Link Hen was attacked by a small dog. She's roaming around with the other three hens, pecking at the ground & everything like normal. I've sprayed her wounds with BluKote already. I have a few concerns: 1) the dog ripped out all her tail feathers, and some feathers on her back, 2) its winter now - it gets to be around 20 degrees F here at night, while they have a protected house with plenty of straw, I'm worried about her getting cold with so many missing feathers; 3) the dog broke & removed some skin - I can see some fat coming out of the wounds, and there's one deep wound that I could probably put my finger into it. We don't have a vet that handles birds in town, will she heal on her own with just being treated with BluKote? Should I bring her inside & separate her from the other birds for a while? Should I just bring her in at night to make sure she stays warm enough? Thank you very much for any ideas you can come up with.
