my 9 week old chicks have been outside for about 2 weeks, it still pretty cool in the day high around 60 degrees and lows around 32 degrees. it looks like it will be that way for another week. so i still have heat lamp in coop. I usually get home from 1st job around 2:00 pm and let them out when it is warmest and put them in the coop before i leave to 2nd job around 630pm. I always have to chase them around and put them up for the night. today it was raining and didn't want to chase them around so i turned the heat lamp on in coop and left for work. I got lucky and got home within an hour or two and hoping they would have gone inside, but they didn't. bye now it was dark and they where really easy to catch. they also have been under constant light since day one and would really like to get them in total darkness at night, but if i turn off the light they just huddle together on floor. so any tips on what to do? at what age can they take colder weather or sleep without heat lamp? oh and last, at what age are they not considered chicks?
