Dried Calciworms are the larvae of the Black Soldier Fly (Hermetia Illucens). They contain around 50 times more calcium than other insects or worms, making them an excellent supplement. Calcium is crucial for maintaining a strong skeletal system, for egg development, muscle contraction, nerve impulses, and a host of other important metabolic systems. They also aid the absorption of phosphorus, another vital mineral for the birds in your garden, and they are high in protein and fat, making them very nutritious and palatable. Dried Calciworms should be fed all year round – particularly in winter and spring, during nesting season.

The number of people feeding birds in their gardens drops in Spring and Summer, the very months when birds need the most support. It’s the period when they are building nests, raising young, and undergoing moulting cycles—activities that require significant energy and reliable food sources.
Poor quality birdfood often contains filler grains, which birds discard and can lead to bacterial and fungal growth. So always use high-quality bird feed such as one from the Johnston & Jeff range.Our suet dumplings are larger and contain almost twice the fat content of inferior brands. These suet and insect offerings of ours provide a healthier nutrition.
You may have read that Greenfinches are in decline, but these attractive garden birds are granivorous and seeds and sunflower hearts are a very important part of their diet. Continuing to feed hearts during spring and summer would be an important way to help.
Refresh water daily and clean feeders weekly. Avoid flat surfaces for feeding as these are less hygienic. Use multiple feeders to reduce overcrowding.
Better quality feed is the responsible way to support UK birdlife and attract a variety of birds to your garden.
