Unfortunately the best thing to do in a case where someone won't accept live animal(s) is rehome it/them(Live animals are a lot of work) Some people aren't cut out for it.I made a guy come get his chicks when he did this to me and he dumped them off on someone else.What kind of chicks are they?
Tell them you will eat them, and see how fast they come get the chicks. (only sorta kidding here)
Seriously, I'd sell as started pullets as soon as they can be out from the heat. You'll get the most money that way for your time and hassle, and won't have to keep feeding them or scooping poop. Craigslist Farm+Garden page where they allow sales of livestock is a place I like to list them. Someone out there will want them. Also try FB farm pages, but they can be funny about only putting prices in PMs.
Also, since these are not pets but are livestock, the other thing you can do, if started pullets are not selling for some reason, is eat them. I have a minimum price I will sell laying hens/started pullets for. I also know how much the grocery store charges per lb of chicken for a whole chicken, and how much it costs to feed them for a day or week, and cost of litter, etc. Processed weight (ready to roast chicken) is about 2/3 of the live weight of a chicken. So I do the math, and if folks aren't willing to pay what started pullets or laying hens are worth, I eat them as a meat bird. But I don't sell my hens or pullets below the costs for raising a meat bird, or I'm losing money out of it.
If I throw the cost of my time into the calculations, I might as well just work more hours at my day job, because I will never make enough money on chickens to pay for my time, but the annoyance factor of having to take care of unwanted/unexpected chicks is high, so you should factor that in some way also.
They all ended up dying or being eaten by predators
