I have 2 Silkie roosters,one Bantam/Barrled Rock,3 Buff Orpingtons,2 Sexlinks,1 Barrled Rock,and 2 Bantams.I was hoping I could get some numbers on how cold each breed can get.Im in Florida,and its getting pretty cold.Like, 65 degrees and lower.Im keeping them pretty warm now, but I want to see if I need to keep them really warm,or they can do without some things.
