Hi Crabby,
welcome to the forum
hope you like it here - it's nice to have a new Robo owner on here
I have been reading through a few of your posts and am a bit confused as to how many you have
- not sure if you have three or 4?
Anyway, regardless of how many you have, you first need to sex all of them correctly and make sure they are all in single sex groups / pairs.
From my experience with breeding in colonies, i have rarely seen them work out well - so if i was you i would separate any females, which have been in contact with a male, into cages of their own.
Robos are very social, and it is not usually a very good idea to keep them singularly, but i have noticed in the past that two pregnant females will usually fight, and all of the babies usually end up in the dominant females nest - sometimes the dominant female will keep the other female away from the nest and sometimes even attack her so that she is unable to feed her own babies
- very sad, and usually rare, but i have see it happen, which is one of the reasons i tend not to breed in colonies anymore.
I think it would be much safer if the females were kept on their own for the next 21 to 25 days, just to make sure they are not pregnant - if they are not pregnant then you can reintroduce them to each other, if they are pregnant then you can let them rear their young in peace and then decide how many babies you are going to keep and split them into same sex pairs or groups - or try different combinations if you need to etc. and reintroduce them to each other if you want to.
While you dont know if any of them are pregnant or not, it will not hurt to feed them high protein food, as everyone else has said.
Roborovskis are not strictly vegetarian - they love meal worms, live or dried, they love well cooked chicken, scrambled egg, boiled egg etc. they also love porridge, baby food, and you can also give them small amounts of fresh fruit and veg - just watch them carefully for signs of upset tummys - then stop feeding immediately.
Don't worry about how much food you give them, they will rarely over feed as long as they have access to a wheel and plenty of toys to keep them active - they will store alot of the food away, so just be careful it doesnt start to go bad - just check their store daily to keep it safe for them.
Good Luck with your Robos.
