You know what it is like waiting for new hens to start laying. It is Jan 11 ,2013. I got these day old RIR. chicks on AUG 15. 2012. LIKE I said they must be really getting set for a big day of egg laying SOON. they should be 20 weeks old This week. ALL 50 of them. wish my new gals luck with the big day. I might need a mid wife with all these new moms!!
