Just how many eggs can she handle?

I am wondering, how many eggs can a broody hen handle? I have a standard size Americauna. She is broody and I just got some peafowl eggs in the mail yesterday. She is setting on some eggs I would like to take those from her and put the peafowl eggs under her. I have 5 of them!!!!! The wonderful man that I brought them from sent me 5 guinea eggs and 7 pheasant eggs!!! (This man is the worlds best seller ever) So I just want to know can my broody handle all of the eggs? 5 peafowl 5 guinea 7 pheasant. 17 eggs!!!!! I know that they can take a lot of eggs but is that too many for her? Thanks so much!

 

I am just worried about the size of the peafowl eggs. They are huge!!! I had no clue that peafowl laid such big eggs. I know that she could handle the guineas and pheasant but the peafowl too? I was praying for another broody and got one but then she "flew the coop" lol When I checked on her she was not on the eggs and was not interested to be on the eggs! I give my hens the royal treatment too, they have a coop of there own, a private nesting box, a non-public waterer, and there own personal food bowl! LOL I didn't even get that special of a treatment when I had my girls!!! LOL I hope that one of my silkies will go broody then I would be no big deal! Oh well, wish me luck and send me prayers Thanks guys!
