Runt or sick?

[Charlene]

These two are about 3 months old. They're just mix breeds from an oops clutch. Is the little one a runt or is she sick? She seems a little slow and sometimes does not roost with the others at night. Because of that she looked cold and sick the other day. We brought her in and warmed her up, and now she is back outside. But is there something wrong with her?

She looks ok to me. The other one looks HUGE for 12 weeks.

If it was a mixed clutch I wouldn't compare her size to the others. If her eyes are clear, she has no nasal discharge, sneezing, congestion or other clear signs of illness I would consider the possibility that she's just different and maturing at her own rate.
Does she eat well?
Encourage her to roost with the others at night, for her own benefit so she can share in the collective warmth. I have to put my runt on the roost each night because she has a vision problem. She'd probably bed down in the shavings and be fine if I didn't, but I think it's best for her to be close to the others.
