I just read, "After 6 to 7 weeks, the keets should be fully feathered and you will be able to turn off the heat lamp. For the last week of heat, turn it off during the daytime only so they still have some gentle heat at night if it gets cold." My keets turned three weeks of age yesterday. It's is 71° outside right now and they are asleep at the open end of the coop in the rain. I've been turning the heat lamp off during the day and I went out earlier to turn the lamp on and discovered them sleeping at the opposite end of the coop from where they normally sleep. The heat lamp is on in the covered end yet they remain, asleep, NOT under the heat lamp. Should I just leave the light off since they are apparently fine with sleeping in the rain without a heat lamp?! Goofy guineas!! hee hee.
