I have a brooder with several chicks in it of varying ages, but one chick seems to not be feathering out or growing. *head scratch* (I hope) SHE has feathers coming in on her wing tips only, and has barely grown since I got her at 2 days old, though she runs around, chirps, fights when I pick her up, eats and drinks on her own and muscles past the much larger chicks to snatch dried meal worms when I give them treats. She is nearly 2 weeks old now and I just don't understand why she seems so runty. She is a blue orpington mix (we weren't sure what the roo is - he looks like a black maran but with a barred tail). Both parents are lf. Should I give her nutridrench? I had put some in the water for all the chicks for 2 days a few days ago, but it was a very small amount. Maybe she needs an individual dose? She seems happy and healthy besides the size and feathering issue!
