I just received a shipment of chicks on Tuesday (25 total). All of them are seemingly doing well, but one is acting lethargic. She doesn't seem to want to move around or chirp like the others. If I pick her up she will cheep as much as the others (and in the same way -- it is not a distress call), but she just sits in the brooder. I have "dipped" her beak and she will drink when I do so, but she does not scurry about at all. If this one is sick should I remove her from the brooder so she doesn't infect the others? Is this common and she'll grow out of it? Has anyone else seen this behavior in 1 out of 25 healthy chicks?
