Hello BYC! I am new to the world of chickens, and I have a similar issue. I have 19 hens and 1 roo. 4 are buffs and the others are red sex linked breeds and maybe red stars (I think). I am still trying to identify them based on the pics you post. The hens are 24 weeks old this week, and no eggs yet. My research of this site tells me I am covering all bases, but I am interested in your opinions. here goes: on laying feed 16% protein, oyster shell mixed in at the ratio suggested on the packaging, fresh water, scratch scattered, and occasional garden scraps - their favorite is cabbage leaves. I live in Wyoming and the summer has been hot, but they have ample shade and the coop is insulated, which kept it fairly cool during the day. Now temps in the 70's during the day and 40's at night. They have had >14 hours daylight, but that is shrinking so I am considering extra lighting in the coop. The coop has 8 nesting boxes, and I put golf balls in there about a month ago. Anything else I missed, or should I just dig up some old fashioned patience?
