Dude, in my humble opinion, you are obsessing about the equipment end of things and ignoring the eggs themselves. With the money and effort you have spent on whirly-gigs, you could have purchased a...

In my hands, males are longer-lived than females and over time I tend to end up with a bunch of bachelors (eh, widowers) which can be swapped-off. Despite the rhetoric about over-worked husbands,...

They will breed at 4-6 months, but the number of offspring is so low that it's hardly worth the effort.
