Hi all. I started out in June w/3 pullets that were eventually murdered by dogs and then replaced w/4 older hens that were aged at about 2/3 years old. The problem is that they don't lay very well or maybe this is typical. I get 2 eggs every other day or so. The last 3 days one of them have come back into lay so I am now getting 3 eggs every other day or so. I have 5 growing boys and buy about 3 dozen eggs every 2 weeks. I am adamant in raising my own egg/food source cuz I know the quality and care that goes into my food source. This is one small food source that I feel I can control. I've seen the sites and pics of the commercial egg producers. I'd like to add 4 pullets, I currently have 2 Barred Rocks and 2 B.O's. I'd like to add 2 Golden Comets and a Black Sex Link and maybe a Black Australop. I'm looking for excellent, x-lg brown egg layers. Would these be good choices? Right now, I've compared my eggs to the grocers as being a Large grade. Thru this site I have learned that my coop needs improvement and that is a daily request for my DH (learned that term from this site also!). So, I plan to make the mods (have them made). My question and dilemma is, can I simply add new girls (after expansions) or would it be best to cull these girls? I proposed to add temp quarters for the new pullets (which won't lay till Sept. and I don't want to go that long w/out my own eggs) and then cull the older ones. So, in summary...how can I easily add new girls and what r the best choices for x-lg, heavy egg producers and BTW does anyone elses significant other think they are obsessed with chickens? What r the symptoms? Thanks for any input. BTW, also thru this site I have found a recipe for homemade yogurt which I plan to try out tomm. I gave my girls sour cream today mixed w/cracked corn and they seemed to love it but then scraped their faces in the ground. Is sour cream ok?
