Hello, new here but not brand new to raising chickens. One of my Buffs has recently torn her comb half off. I have seen some other posts here that talk about “dubbing” or cutting the comb. I am unsure how to go about this or where exactly to cut? Is there any harm in just leaving the way it is. I have read they need it to regulate their heat and I live somewhere where it is quite hot in the summer months. Thanks in advance for any input.
