She does have pasty butt, and I check her bottom twice a day. She does eat but I think because she so much smaller she gets pushed out of the way. I’ve given her a small amount of vit c but she just cheeps like she’s stressed. I’ll wet down the mash and offer her some but she’s just so sleepy...I would check her for pasty butt, give her the vitamins and maybe give her and the rest of the chicks a wet mash from chick crumbles. That should make it easier to eat. Make sure she gets a fair share of food and water. I would eep her with the others as long as they are not harming her. I have a GLW runt who started out like that and is still a little bit like that at 15 weeks. She's small but pretty competent.
