I have 9 chicks in this cage, they will all be standard size hens. The cage is 2.25 x 3.5. How long can I feasibly keep them in here?They are now about 1.5 weeks old. The temps outside will be mid 70s to mid 40s this week so hoping the warming trends up soon. I have a very large coop that we are in the process of cleaning and repainting so it’s not quite ready to use.
