Yeah they are the sil go sex link. They are great layers and pretty cheap compared to most hatcheries. I have a friend who has the parent stock for a RSL (RIR x Delaware) and I have hatched my own this year but i will probably order from central next year. It is much easier to have all of the birds the same age. My birds are about 3-4 weeks apart in age and its time consuming when they are more than 2 weeks apart. Because of heating.
A 50x40 barn is huge! Do you sell a lot of eating eggs?
