four weeks ago.. i purchased three americaunas from a local farm supply store. To go along with my other five chicks I bought from mypetchicken.com. Now like any new chicken owner I have been watching them VERY CAREFULLY. One of the americaunas.. is very aggressive and thick legged with a bump or nipple looking thing ofn the back of both legs. The RIR rooster and him are staring it down lately.. almost bowing to each other ... If this is a rooster....it's not something I would like to tangle with. I made sure I asked the women at the store that these are actually all hens.. she said yes...help... what can I do..or is it too early really to tell anything..
