$35 is fair. What would it cost to replace your hen with a comparable hen? Or what would it cost you to buy and grow a new one? In that case, you are out the time and cost it took to grow the first hen, and now the time and cost for the secon (replacement) one. You see what I am saying? She should be glad to pay for a replacement hen that is grown, thats cheaper than paying for a chick and the time/cost to grow it.
