My chicks will likely be ready to move out to their coop in the next couple weeks. Their brooder is in our uninsulated garage and they have been without a heat lamp for a bunch of days. Last night we had our first frost (UGH!) so I gave them a tiny bit of heat in their brooder. We've also been spending some time out in the run during the day during cooler weather I am not planning on supplying heat in the coop. Once they are fully feathered and out there. - what temp do I need to worry about? Now that we've had our first frost I'm feeling more pressure to get them out there sooner than later!
