Is it possible to have a silent 'roo? I ordered a bunch of day old pullets but ended up with one 'roo mixed in, a partridge Plymouth Rock. He's now 15 weeks old and I haven't heard a single sound out of him. Meanwhile I have a Serama cockerel that started crowing at week 9. Seramas are one thing, they only crow a couple times a day and sound like a broken toy, but I am afraid a heavy breed is another thing altogether! If he starts crowing I'll be needing to find him a home - my neighbors just won't appreciate the noise, so I am probably naively hoping he's just bookish or something. Also as you can tell by the photo my hens are plucking his tail feathers. Can I discourage this somehow? He's the only one they do it to...
