Ok I am so confused. I have a chicken pen full of what I thought were all hens. 4 of them we hatched out this summer and the other 8 are definitely hens. Our daddy roo died this summer after I had given all of the chicks that I was sure were roos away. I kept 4 of the chicks that I was sure were pullets, but now that I have gone and gotten another roo, I'm not so sure anymore. I am afraid I may have 2 hens and 2 roos. The 2 in question had slow comb growth and have not made one attempt to crow even though one of the other chicks (that I gave away) was crowing at 2 weeks of age. So I figured if they are not crowing by now they are surely hens. We hold and play with our chickens routinly so I was surprised to notice the bumps on the insides of their legs tonight. This is what has me questioning their gender. I've never seen them do anything rooish. And they run from the older hens all the time. I so hope they aren't roos because we are madly in love with one of them.
