It is very important that your budgerigar is getting enough vitamins, you can buy vitamin drops that you add to their water to help to them up. Other important minerals come from cuttlefish bone, which provides vital calcium. You can buy cuttlefish and clip it to the side of the cage, always make sure there is cuttlefish bone inside the cage, as they will also use this for cleaning their beak. If you buy a cuttlefish from the shop you should be able to put it straight into the cage, if you pick one up from the beach, you will need to clean, boil it for an hour and then leave to soak for a whole week, changing the water it is soaking in every day.
Budgerigars like other birds do not have any teeth, so they need to swallow grit to help grind up the food inside their gizzard (a part of the birds stomach). You should always have grit available to your budgie either in a separate tray or amply sprinkled onto the floor of the cage.
The amount of a food a budgerigar will eat will vary from bird to bird. It depends on how active they are, their age and their own personal appetite. You must always make sure there is food in the cage at all times, budgies don't eat at a set time, they eat little amounts often and rarely overeat unless they are lonely or bored and not stimulated. If you follow this plan you will know that you are giving the correct amount of food to your budgie.
In the morning you should clean out their dishes and fill them with fresh seeds, empty and rinse out their water container and fill it with fresh clean water.
A few times a day you can remove the empty husks from the seed container, blow them off or scoop them out with a small spoon then top it up with fresh seeds. If you know you are not going to be home all day long then you should put 2 food containers inside the cage, sometime budgies cannot find new seeds underneath a pile of empty husks.
Every other day offer your budgerigar a small selection of green foods and or fruits.
You should never give your budgerigar scraps of food from the kitchen, or chocolate or sweets. Never let the seeds go mouldy, if they do, do not feed them to the bird. Do not give them frozen or canned fruits all fruits and green food should be served at room temperature, so don't hand them anything straight from the fridge. Finally never gather any plants you find on the side of the road because the pollution could cause harm.
