Our guinea pigs have fallen out?

[Moveonup]

We have two male guinea pigs that we bought about four weeks ago along with a new indoor cage and bedding etc. Both guinea pigs have seemed really happy however this weekend we noticed one of them had not come out much. We gave them both a cuddle for a while and put them back in, this time as they were both out together they had a fight. Most of the time one pig has been inside and the other just sat outside the door. At first I thought one was not letting the other out, but now I think the one inside is not letting the other in. If they get too close to each other they have had a bit of a stand off, making clicking noise at each other.

I am concerned now the one inside may be a bit poorly. Is there anything I should do? Is this behaviour unusual?

Thanks

We have not noticed anything, I will have a very thorough check tonight.

Is there in room in the cage to put another house so that the other pig has somewhere he can go, i have two young GP and even though they get on well I have two houses so their still each have their own space and it seems to work out well.

Looks like your boys have struck the stroppy age between 4-10 months old when the hormones really wake up.

Make sure that you have everything in twos - hides, bowls, water bottles, hay racks, so that access to food and a sleeping area is not an issue and cannot spark another fight.
