Here's the deal on broodies...
They MAY NOT want to sit on eggs for you.
Sure you can purchase silkies... and get your eggs and they decide "Nope, don't wanna sit on them."
Usually how it works.
Another deal is, you could have this happen....
Place $150 eggs under a broody hen who happened to be broody...
And then week 1 1/2, she poos ALL OVER them and leaves them...
Ruins them all...
And then a week after they're due to hatch (mind you, you've had to throw them all aways, because you put them in the bator and they begin exploding)
you get TEN broody hens who go broody
Mind ALL love hatching mutt eggs... any expensive eggs and they avoid them like the plague!
