Hi all, I have 3 adorable chicks that we have had since they were 72 hours old and who are now 5 1/2 weeks. We have had them inside in a 4 x 4 foot covered pen. 1 Cochin, 1 Barnvelder and 1 Cuckoo Maran. All Hens hopefully. We have a 60 watt light bulb lamp on them when the temp goes under 75 at this point. They seem comfortable and playful. Their feathers are getting fuller by day. They are flying up and around the pen now and digging up their paper towels as they would do outside in the dirt. When can we put them outside? It's warm here but at night it gets cold. We are in Northern CA. East Bay area.
