Hi. My silkie is about 6 months old now and I had always assumed it was a pullet (especially since I got two of them at the time and the other one made itself known it was a cokerel at 12 weeks). But this morning it let out about a half crow. It's waddles have seemed to double in size in the last 2 weeks. It has always kept to itself and left my other hens alone. So I'm wondering if I have yet another rooster on my hands?
