Total amateur here. My gf in Vietnam hatched a baby chicken, and it was doing great, and always walking around normally, but now will only stay in (admittedly makeshift) brooder, and no longer walk around. Has no obvious deformities or injuries, and chirps robustly, but no longer wants to move, and she says he’s losing strength. I’m educating myself furiously, but believe best source of info is experts with experience, so I’m posting here for advice. Again, I know nothing, total newbie, but my gal is really emotionally invested in this baby chick making it.
