It's early days yet with your hubby. Our situation was much the same. The first couple of weeks, Timber would go straight in his cage when Gary came in the room. He would stop and talk to him, even give him treats which he would accept, but his tail feathers were quivering with fear/nervousness. Now, while Gary isn't able to scratch him or get a step up, Timber doesn't flee at the sight of him and doesn't get upset when he is around. Just this morning, Gary said Timber said "Hi" to him when he came downstairs. My point being, it just takes time in most cases. Others may have more advice on how your husband can "make friends." You might, for instance, let your husband and him alone give him his most favorite treat. I told Gary he needs to whistle at him and always speak when he goes by.
