My two peckin female ducks share a coop with my 9 chickens. They are all locked up in their coop at night together. It's been getting to about 35 degrees at night so far. I have three RIRs, two americanas, three sex links and one leghorn. I have a red heat lamp in the coop but I'm not sure when to turn it on and if the ducks require the same heat. I have no way to separate them. We bought them all together at the same time. I'm just not sure if they are warm enough and want to make sure everyone is happy.
