I have 2 RIR Roosters and 11 RIR Hens. And a Bantam Rose Comb Rooster. A few months ago a dog broke into our chicken coop and killed 12 of my hens. They were all around 3 months old. I have read that RIR roosters are very protective of their hens. When this happened they were all hiding in a corner on their nests. Is this because they were so young? I don't know alot about RIR's so I appreciate any info I can get. Thanks
