Ok I'm new here and I'm learning the language I figured out RIR means Rhode Island Red, along with many other abbreviations for Chicken Breeds i.e. BR and Crested, I've also managed to figure out what people are talking about when they say 'brooder' and my Broody hen,but for the life of me I can't figure out why people refer to what I think is their husbands as DH??? What does this mean?? And if there are any other abbreviations I should know please HELP!!!
