Hi all , after some advice. I have two Nederland brothers. 1 has just reached sexual maturity and has started being amorous with his brother , who is getting very fed up. They are booked in to be neutered on the 18th . I have just separated them temporarily as I was worried they may get aggressive. But they are looking for one another. The other brother is still too little to be neutered as only 800 grams and not yet 4 months. Have I done the right thing or should I put them back together . Appreciate some advice thanks in advance .
