Depends on how you look at it, and what you want from this girl. I had ISA brown for many many years. They'd lay every day, not even stopping to molt, or to take a winter break, and then after two to three years, crash. One year later or so, and they'd die from a reproductive issue. I don't...
I do! She might mature a little more before laying her first egg, but she looks so much better, and more able to take on egg laying! Hopefully she doesn't take from her mom's egg laying abilities
Cold doesn't really play a role unless you get into the extremes. We feel like it's cold, but it's Greek cold, not Canadian cold ;) . She'll likely lay soon
