Seeking to rehome five 2-year old chickens (2 Easter eggers, 3 Bielefelders) in the Denver area to a good home and will provide all supplies - including two large waterers (one metal incl. an electric heater for winter and a plastic one for summer), coop warming panel, two automatic coop doors...
My chicks are ~4 days old and one is tucking her head under her body (almost biting at herself?) and running backwards. I checked her body and was unable to find anything that could cause this and her vent is clear. I've included a video of this behavior, but sometimes it is worse (lasts longer)...
