On June 6th my cousin came to my house with 4 green/brown eggs and only two survived but I have no idea what sex or breed they are. My cousin found these eggs in him moms yard while mowing her grass and came a cross these eggs. We are very new at raising chickens and we live in the city limits where we can not have roasters. so far these babies are about 21 weeks old and have not laid any eggs yet. Is there any way some one can help my identify them and maybe tell me some facts as to when they might lay some eggs.
