Have 6 Rode Island red chicks in five-week all have most of the feathers but one looks to be molting. Just as active as the rest but not sure to keep this one with the rest. Is she sick or what? Any help would be welcome. Thank you all so much
The chick is losing its baby fluff and is now gaining its teenage/adult feathers, nothing to be concerned about, some chicks just like hens molt harder than each other.
