8wk old broiler rescue pls help

’ve inherited a 8wk old broiler from the local chicken farm last Sunday - and we called her Sunday lol. Guy from farm appeared on doorstep (I have other chooks) and said she didn’t make grade weight for slaughter but he felt she was too good just to kill so he thought he’d bring her to me! She was quite lethargic the first day and obviously stressed, she’s improved over the last few days drinking and eating and is being quiet social. She’s partially feathered so I’m keeping her inside away from my other chickens for the time being - thinking a months quarantine. I’m just looking for any suggestions about her care etc any help greatly appreciated.

she   or he may struggle as it gets a bit older these birds are genetically designed to have short life
they sometimes struggle to support there weight   wish you luck hope it goes well
