Hi Everyone!! So my boyfriend and I are ready too add a few more members to our flock!! We want to add maybe 2-3 more (we currently have 3; (2) 3 month old Silver Laced Wyandottes and (1) 2 year old Buff Brahma). We have a choice between Black Star, Barred Rock, Buff Orpington, and Dominique. They are all between 14-18 weeks old. Which breed(s) is/are the best layers and most friendly? I have a plan on how to separate them for a few weeks in the run, but I am also worried about them getting cold while the other Chickens have the insulated coop!! We live in Colorado so it tends to get PRETTY DANG COLD some nights! Any advice and tips would be appreciated Here is a picture of where I will be putting the new girls; I will put hardware cloth along the entire opening and that will be their little section until they all are used to each other (the area under the coop). I will be putting a heated waterer and feed in there. I was thinking of putting a dog kennel filled with straw in there as well so they have somewhere warm? thoughts? Is that a bad habit to start because then maybe they will sleep in the nesting boxes?
