Do i keep trying to get my ferret out of its cage?

i bought 2 new ferrets on monday,they were well handled when i got them at first there were no problems.now when i go to get them out of their cage one of them is a bit jumpy and she has lunged at me a few times,i dont know if this is play or if she means to attack me she hasnt caught me yet,do i keep trying to take her out? the other one comes to the door when i open it and is fine apart from the normal play nipping,when they are both out they are both happy to be picked up its just getting the jumpy one to come out thats the problem!! what should i do??
