Our chicks will be 4 weeks old on Monday and are currently residing in our bathtub We have guests coming next weekend and need to get them out of the guest bathroom and into the coop. They are getting lots of feathers but still have fuzz on heads and undersides. The temperatures next week will still be pretty cold at night (26-32 degrees). My initial though is that is still too cold for them to not have a heat source so my plan is to run an extension cord and put their heat plate in the coop so they have a source of heat. Does that sound OK? Any other ways to make sure they stay warm enough? Don't want to go out one morning and find chick-sicles.
