Rescue 2 Boars Together Now They Are Fighting? :(

[Faith1996]

I adopted two boars that were paired together, jethro and leroy from a Guinea pig rescue near me and am getting a little concerned about leroys behaviours towards jethro.
Leroy has been getting very aggressive towards jethro; biting him continuously, mounting him, not letting him drink or eat much, pushing him out of the way etc. Jethro is starting to whine so much and runs away from leroy.

What should I do about this? At first I thought it was down to stress from moving but I'm not sure has anyone got any ideas on what to do please?

Do they have at least two of everything? Food bowls, water bottles, hidey houses etc? How big is there cage?

they have two food bowls and plenty of space to be away from each other. I put them out in the run for about 3 hours a day as well

Hi and welcome! How old are your boys and how long have you had them?

Hi! They are both around 20 months old and only for a week. I'm a first time Guinea pig owner so not sure what to do

What your boys are doing at the moment, is re-establishing their hierarchy in new territory.
Please make sure that you have everything in twos, bowls, water bottles and hideys as well as more than one access to hay or mor than one hay rack; iseall each same item space well apart from the other, so that it cannot be blocked. I would also recommend to only use hideys with two exits at the moment, so that the underpig can't be "locked in" for the time being. Log tunnels or houses are suitable.
Chucking the underpiggy off food and out of the hidey is normal dominance behaviour, as is mounting, nipping (a carefully judged gesture of power that just lets the underpiggy feel the teeth, but that does not break the skin) etc. The whining that you are hearing from the other boar is not pain, but submission. it is generally quite effective. The behaviour should settle slowly down over the next week or two. None of the behaviours that you are seeing are in the highly aggressive range.
