I lost one of my 4 week old NHR chicks last night. All others seem fine, they were all sitting away from the body when I got up this morning. Only thing different was that I offered them a few meal worms yesterday afternoon for the first time. Not too many (approx. 20-30 worms for 14 chicks). Maybe this one ate most of them and got sick? Looks like the chicks pecked at her head after she died. Yuck.
