Hi there, Iíve had buddy for 6 years now! And Casper for nearly 2 theyíve got on so well from the start but Casper has started to pluck buddyís head. I noticed that he was grooming him more but didnít notice until yesterday that buddy now has a huge bald spot! Iíve separated them both but feel like a bad bird mother because buddy is now in a tiny cage! When I let them out today Casper straight away started to try and pluck him again. Any advice on how to prevent this happening? They get on so well that I donít want them to be separated for too long! Thank you.
