Absolutely amazing product. Who says Pigeons can not use it. I saw two pigeons dancing on the top hut. At least 8 to 10 pigeons were seen today morning enjoying to use this. There is absolutely no issue with plastic, it is as good as any cold drink bottle we use. I am really excited to tell you all that it is a well designed product. No wastage of feed. In fact, they are avoiding the earthen pot full of feed placed nearby. 😃😅...But yes, it took my birds 2-3 days to adopt it.
