I am fascinated too! I have some chicks in the broody at the mo and more in the incubator, I just love it, although, this year I am having to time hatching with being fully feathered for the sales, or, OH might just be sending me to a sale instead! After this lot (guinea fowl) am going to set some of my White Campbell eggs, is all goes well will either hatch more to sell or try hatching eggs.
I just love my incubator, watching them hatch and rearing them, if a hen goes broody of course, she can do the job and save me the electric bill!
