Well chameleons with benefits when they housing together now she is gravid with his baby eggs,I will suggest find her a separate cage asap,since housing together will only cause both chams in tremendous stress constantly and possible make her have egg bound even cause her to die.assuming she is gravid 4weeks ago,she probably will lay her eggs in a month more or less,time is ticking,the choice will be up to u to find her the separate cage n setting up a laying bin for her laying purpose,if u want her to be well.
