Thank you.
Usually I feed her pigeon and chicken meat, and Lavet calcium tablets (crushed into dust, on the meat). I know a few pigeon breeders, who sell their pigeons with a friendly price (huge discount), because they know that I use the pigeons to feed my hawk (some people buy pigeons to resell them).
Otherwise a whole pigeon would be very expensive. For example I buy pigeons for around 200-300 HUF ($0.63 USD - $0.95 USD). Some breeders kill the pigeon in front of me, so I get a fresh, literally a warm pigeon. The normal pigeon price would be around 500-1000 HUF ($1.58 USD - $3.17 USD), and sometimes even more, depending on the type of the pigeon. One pigeon is usually enough for her for 1-2 days. And for more days, if the weather is hot.
So usually her food would be around $10 USD and $30 USD per month, if I would feed him clearly on pigeons. The mixed diet is somewhat cheaper, because the chicken meat is cheaper. I buy the chicken meat in the stores, not from breeders.
Usually I can feed her for around $10 USD - $20 USD per month.
Have a nice day. All the best. Greetings and much love from Hungary.
