How do i get a second nest?

[gravityperseus1325]

Its just so dang expensive!!!!!! I mean, 240 gold. I get like 1 gold per day...u telling me I shud wait for 240 days?! And some days I don't even get anything. TL should reduce the price of the second nest to around 24 gold (here's hoping). Why do they have to charge so much?!

1 nest is free, second nest is 250 gold and third nest is 500 gold...I wonder what the fourth nest cost:(
