We've got Buffs, cinnamon queens, Australorps, Speckled Sussex, Marins, Welsummers Americanas and a few others. 18 birds that are strictly for egg production. We have done broilers as well.
Which, at this point, is out of control. More daylight and warmer temps in NH has them producing a dozen a day or more.
Hawks, owls, fox, mink/weasels, and coyote are the big problems here. I built a 20x20 chain link enclosure, covered, to protect them. Before that, we were losing a bird a week to some type of predation. The dogs do a good job, but when we're not home.
