I keep one breed at a time since I don't want interbreeding and the added work to separate. The last 2 have been on the endangered or watch list and heritage breeds. Out of Buff Orpington, Dominique and Salmon Faverolle I liked the buffs best for eggs ( big and flavorful) and being good sitters...
Here are mine at 3 days old. They're 4 weeks now. Friendly and active. They love it when I go inside their area, come running and talking, wanting to be touched.
