I got these chicks about 3 days ago at TSC. The gentleman there could only tell me they were day old red pullets, had 3 possible breeds on the sign. He was nice enough to check them to make sure they were all females. No comment on that one. Question one being as I have had them 3 days and looking at their wing feathers how old do you think they really are? That brings us to question 2. How old should they be before going into a chicken coop/run with them as sole occupants? I do live in Texas and we are having an unusally warm winter here. It's been getting into the mid 70's in the day and dropping into the mid 40's at night.
