We don't leave food in henry's cage overnight because it attracts nocturnal rodents and insects. We take the opportunity to train Henry before breakfast, because he is hungry and will be motivated for a food treat and feel that we get better results. We only feed Henry a set amount of food each day this is two meals a day with some foraging food toys between meals. Henry will also get a five minute training session before his dinner. I disagree about always having food available to any animal, all this does is cause animals to over eat and become FAT. Henry will tell us when it's dinner time. He actually tells us "dinner time".
I have found that birds will prefer to sit and preen themselves after eating a meal and are not motivated to train regardless of what reward is offered.
