To use this Hagen Finch Seed, simply fill your bird's feeder with the seed mixture. It can be the main part of your finch's diet for a long time. You can also mix it up by giving your finch some Hagen treat seeds or fresh greens every now and then. Make sure to keep the feeder clean. Wash it regularly to prevent the growth of bacteria. Check the seed supply daily and refill when it's low. If your finch starts to be choosy about the seeds it eats, add a balanced vitamin supplement like Prime to the diet. This can help keep your finch healthy and happy.
