I would like to take the time to introduce myself. I am new to chickens. I have been wanting some chickens for some time now. My twins hatched these in the 1st grade. They are Tyson chicks, don't know what they are? Breed or sex. I scored a shopping cart holder from our local Dollar General store. The run is about 3' L X2' H X 18" W. The house is the same dimensions. I know this is not big enough for them, it is only temporary. They were making such a mess in there brooder. I will be taking a step-by-step picture essay of my chicken tractor that I will be building. I will be posting pics and dimensions. I really enjoy the forums and if anybody lives in the Lynchburg, Tn. area shoot me a e-mail.
