I have a mini barred rock who should be around 4 months (from what I was told) she is inside with one of our injured frizzle (doing fine). They are best buds. I have noticed ZhaZha (barred rock) doing quite a bit of scratching the bottom of their enclosure, laying down, wiggling a bit, chirping then she'll sit still for a few minutes, get up and do it all over again. Blondie (frizzle) gives off her protective clucking once Zha Zha lays down. Is this normal???
