Reassure another newbie about their brooder please (pics)

My wife got a kick out of the brooder with the toys for the chicks. The only suggestion I have is possibly move the light off the wall of the playhouse so it doesn't melt the plastic.

It doesn't need to be 95 everywhere, like you said so they can snuggle if need be, they also need to be able to get away from the heat if it is too warm...

Also a newbie here and expecting my chicks delivered around April7th. I'm creating a brooder out of a rabbit cage for my 5 australorp and 5 barred rock babies. Wish i had playhouse...so cute!

I had one quick question, how big do nesting boxes have to be?
