These guys (hopefully gals) were feathering out at TSC crammed in the new brooders body to body when I got them. They didn't know the age. I think we have had them 2 weeks now? Any guesses on age? I have them at house temperature (in the bathroom near a heater that pops on on colder nights). They are thriving. I was thinking 4 or 5 weeks-ish? Anyone know?
