Kev, can you post info on the single comb NN line you had that laid blue eggs? I've got some blue egg layers growing out here - Cream Legbar cross- but the colors and size are "meh". Wondering if your line of blue egg laying NN's could be helpful? As if I need a side project - sigh!
OOps, completely forgot about your question, sorry.. as it is I got to run and pick up baby chicks a friend hatched for me.. have severe chicken dander allergies so I cannot have an incubator in the house.. Will try to remember this time.
