I have 24 adorable but annoying little peepers who were born on 1-7. I changed their light to a 60 watt and they are doing fine with that, not even sure if they need it anymore. My second order of chicks is shipping on the 28th of this month, so I'd like to get them outside as soon as possible. When do yall think they will be old enough to be outside? I have a great place to keep them, and can keep a light on them (100 watt?). It's usually 50s during the day and 30s at night but sometimes gets below 20 at night. TIA!
