Hi again lisalisa
To train Benji we kept going out into the garden where he likes to roam at present. Approaching him very slowly and gently and offering him carrots and treats. That way they get used to the fact that you are there to be kind not as an enemy. He slowly got used to the idea of the treats and now comes to us.
He does occasionally still get aggressive, we started at first with my husband approaching him, when he got used to him, then myself and soon it will be the children. I think children are a bit unpredictable to an animal and the animal senses this. So might be best to train the children (in the nicest possible sense!) we had to with ours.
Do remember tho that they can be very territorial animals (the rabbit that is not the kids!) and that they do get hormonal (like us women I suppose).
Also to Twinkie if your rabbit has the runs(no pun meant) it should be looked at within fairly quickly if it has been more that 24/36 hours as this can lead to bunny death very quickly.
Gl with your next bunny if you decide to get one lisalisa.
