I have a flock of 12 ladies, 2 years old next month. Different breeds. My black buffs are gorgeous! But my RIR's are moulting? I dunno, but they look horrible. Is a spring molt common? If it were mites wouldn't it be the entire flock. Egg production is maybe 4 eggs a day. I have never gotten a full basket from this flock. It's depressing to keep putting out for feed, maintaing the coop and buy eggs. I appreciate any and all help or advice you can offer me.
