Egg producer distributes supply at random (8)

I believe the answer is:

platypus

I'm a little stuck... Click here to teach me more about this clue!

'egg producer distributes' is the definition.
I can't tell whether this defines the answer.

'supply at random' is the wordplay.
'random' indicates an anagram.
'supply'+'at'='supplyat'
'supplyat' is an anagram of 'PLATYPUS'.

Can you help me to learn more?

(Other definitions for platypus that I've seen before include "Australian resident" , "river creature" , "Aquatic creature" , "Aussie creature" , "venomous mammal" .)

I've seen this clue in The Globe and Mail.
