I have seen that some of you hatch all year round....so I was wondering. How long to you have to keep them in the house before you put them in the chicken coop? I have some 7 week olds in a separate pen with a heatlamp 24/7 in the coop that are doing well. I could partition it off to have two pens with a heat lamp each, but with the freezing weather we get from dec-march in Iowa I would think a new hatch would have to be at least 8 weeks until you put them in the coop? My second question is that I have some 7 month old dorkings that have been laying for about a month. Since I have never had dorkings before, I don't know if medium sized eggs is normal, or if they will get bigger with time....could I put them in the inci now??? Thanks! It sure would be fun to time some Christmas chicks for my Grandchildren!
