I'm sure there are many posts like this but I haven't been able to find any specific answers yet. My chickies are 3-4 weeks old. They are almost fully feathered besides their heads and parts of their backs. I've been keeping them in the house and still have a heat lamp on them, but have decreased the temperature every week. They are starting to get more brave and this is the first week they have not freaked out while I handle them. They are also getting more curious and jump out of their box every once in a while. It's been rainy the past 2 weeks and I don't plan to let them out until the rain stops. I also have a separate cage to go inside the run so my year old hens can get used to them being around. I'm really just wondering when is safe for me to turn off the heating lamp, and also when I can put them outside, and when they can sleep outside? Any thoughts would be helpful!
