The badly wounded one is missing the skin down to the meat on her back from either a hawk or my dog and the other was attacked by dog and has a small wound.
Ah ok. Are the injured birds pecking the wounds themselves or are other birds?
One is pecking herself and I saw her peck the severely injured one as well. I keep the separate most of the time with the more injured in a kennel but I don't want her cooped up all the time.
as I am a big big night crocheter as well. Maybe do it for protection but if it's roos that are doing it, your gonna want to do single crochets all around, cause if a toe nail got stuck in there.... 
Bad thing may happen. I want to crochet my chickens hammocks and other stupid stuff like that but I'm just terrified of their nails getting caught in it and then they freak out and end up just getting stuck until I can save them... Then again I'm a huge worry wart.. .
Yea.... i am worried about the nails as well. But, it not for heat it is for protection from pecking. I plan on keeping the 2 injured inside till they heel. But, I don't want them pecking each other.Sweaters actually don't help keep chickens warm, it prevents it because they need to be able to ruffle their feathers and such. A huge disappointment
I think that's a great idea and they'll have supervision and be safe. Having them outdoor s... Well more things to get caught on
I plan on putting gauze under sweater along with triple antibiotic ointment to prevent sticking. I am going to use cotton yarn so it is not so abrasive.
