Not eating

[Adictv]

i have 3 pygmy bearded dragons 2 male 1 female they have always been together now that the female has mated i put her in another tank to stop over breeding she was fine for 3-4 days but now wont go near any food and just sits under her light. is this a sign she will lay soon or should i put her back with the other 2?
Sorry about the beardy question
