I have a 4-5 month old veiled, she would turn gravid colors such as black with yellowish lines and dots, but only for a couple minutes then goes back to green, I just don't know.
Does she look chubby to u?? Do u have a food scale at home?if u do,plz weight her,and record all her weight,usually when she is gravid,the weight will start increases day by day,just to be sure,u will have to put a laying bin inside her cage since she is at that laying age!
