Hi everyone. This may be a dumb question that has been asked a million times, but I just moved my chicks into the coop at 9 weeks old. It is only 2 of them, on their own roost because my guinea is not very nice to them and especially does not like sharing a roost just yet so no warm cuddles from the big girls. It is going to be a LOW 32 degrees tonight and I'm wondering if they need a heat lamp? I live in Washington and the weather is crazy. Any help is appreciated.
