Would like a speedy response please.........

I managed to hatch 1 chick from a home made incubator nearly 2 weeks ago, he/she is doing very well. I also have a clocker/broody hen sitting on eggs that were due today, but still havent hatched. If these eggs dont hatch, is there any chance of me putting my 2 week old chick in with the hen that was sitting and she will look after it?
