Some croc advice needed please

[o-lara-o]

Hey guys,
I have recently bought a saltwater crocodile juvenile approximately 18 months old and am struggling to get him to eat anything at all. Was just wondering if anyone has any tips for me. Croc keepers here in Australia are pretty few and far between and no one has any advice for me. Even the farm I bought him from isn't of any help to me either which is disappointing.

So far I have tried mice, chopped up whole baby chicken, shrimp, crayfish and chicken necks (Which is what the farm told me he was eating). I've offered to him on tongs as well as leaving food out for him overnight.

We've tried to reduce stress as much as possible. He is in an above ground heated pond with a large land area with basking light. We have only handled him a couple of times to clean out his pond and are trying to minimalise any visual or physical contact with him until he starts eating for us. He had a powerhead pump in the pond to assist the canister filter however we felt that the vibrations it caused may have been causing him added stress and have had that pump turned off for just under a week now.

Does anyone have any tips they could share from experience?
Thanks in advance
