I just recently adopted a lost Homer Racer, that will be kept as a 'pet' by us...
After doing a lot of research and some hands on, I fully endorse the practice of feeding it twice a day...
At first our pigeon was offered free choice, it only ate the most desirable grains it wanted and tossed the rest on the floor, it would literally empty an entire bowl of food in minutes just picking out the desirable stuff it wanted to eat, a huge waste of feed and not a balanced intake...
We now feed it one tablespoon of feed morning and one tablespoon at night and there is zero waste, it eats all the grains and empties the bowl with each feeding...
As touched upon by others above finding pigeon feed can be hard in some areas, I have no problem finding it in my area but only in 50lb bags with a high cost and that is overkill for a single bird, so I set out to mix my own using stuff I can readily and easily obtain at local stores... I make no claims on this being a perfectly balanced diet, but i suspect it's pretty close..
Do note that pigeons need light to synthesize vitamins so pet pigeons need to be outdoors, by a window or be provided artificial full spectrum lighting to be healthy...
This is my feed mix, from easy to obtain items at
Walmart and/or the local grocery stores...
I started with a 7lb bag of wild bird feed, to be specific it was Pennington Select Birders Blend... I chose this one because it was one of the few wild bird feeds with a nice variety of whole grains and no byproducts or filler corn...
Ingredients: White Proso Millet, Sunflower Seed, Safflower Seed, Wheat, Milo, Calcium Carbonate, Vitamin A Supplement, Vitamin D-3 Supplement, Potassium Iodide, Vegetable Oil
It was a 7 pound bag that started at 10% min. protein
I added
1/2 lb popcorn @ 11%
2 lbs lentils @ 26%
1 lb wild rice @ 15%
2 lbs dried whole and split peas @ 25%
1 lb barley @ 10%
1/2 lb whole oats @14%
and a dusting of Diamond V XP food supplement, as I have it on hand as a supplement to young birds, it's a great feed supplement loaded with vitamins, if you don't want to buy this you could substitute some other bird vitamin powder mix from the pet store...
That puts the feed at about 15% protein overall, with a nice mix of grains and if rationed out morning and evening the bird eats it entirely...
