Ok I know I have posted this before but I didnt get much feed back. I think my chickens are about 20 weeks old now and from what I am hearing they start about this age. Well the thing is is that mine have NOT and it is driving me crazy. We are not sure but we think we have only one hen but from what I can see we might have 2. None of them make the roo sound at all and by know if they were roos they would have wouldnt you think. I have also heard that hens mature and grow faster then roos if so then maybe I ony have 1 roo. I am so confused as to what we have. All I know is we have chickens. So can someone please help me to figure out what I have and why they are not laying yet.. I have put golf balls in the nests to see if that works but i only did it today. I know the white one is a roo for sure he makes the roo sounds.
