Hello and a big warm welcome to the forum,
Congratulations on your new arrivals, its an exciting time becoming a piggie parent!

Talking and discussions of breeding, showing and planning breeding is not allowed on this forum, as been explained to you...we are rescue friendly!
The forum has lots of helpful advice, threads and information from healthcare, toys, behaviour to food and housing. If you take a look around you can find all the basics on piggie care.
Guinea pigs can live to eight years and more, so they are a
life long commitment so consideration needs to be taken whether you can afford or want them for the foreseeable future. I'd strongly suggest setting up a 'vet fund' and putting some pennies away every week, as piggies are prone to illness just like any other animal to illnesses!
I have boars which live outdoors, so you can keep them outdoors but care must be taken to keep them warm and not in danger to becoming ill with cold related illnesses. My boys are kept in a shed, if possible you might want to consider putting them in an unused garage or shed with a window if you have one? This will keep them sheltered from the wind and rain, if they are kept in a shed/garage/outdoors i'd suggest buying a hutch cover or snuggle, or making your own (i use loft insulations and several layers of blankets).
You will need to separate the male and female, as you will end up with the female possibly pregnant and in danger esp if shes not had pups before. Another hutch will be needed, you could consider neutering the male so he can live with the female, quite a few rescues neuter their males so you could give a rescue near you a ring and see what vet they use as not all vets are cavy savy! Or another option is if you dont want to neuter the boy is to go to a local rescue and try boar and sow dating to find them a friend of their own gender, piggies should always be kept in pairs/groups as they are a herd animal and can become lonely and depressed on their own.
Feeding, you will need to give them unlimited amount of hay daily, alongside fresh fruit and veggies (as guinea's cant make their own vit. c) you may also consider giving them an egg cup full of pellets daily too. Any pet shop sugar treats should be given occasionally as they are full of sugar.
If you look in our housing section you can find a lot of reviews on housing and bedding which is suitable for you. If your housing the piggies on sawdust and hay they will need soiled bedding changed daily, and a thorough clean out once a week.
Piggies need exercise and space to explore and play so a run will be needed for outdoor and indoor play, toys should also be given to keep them occupied!
Hope this helps, please feel free to ask any more questions
