I want to get into pigeons, just the plain ones and they are very hard to find. Also, what kind of pen do they need and any special feed? I see that many let theirs free range but how do you get them back into the cage? How many babies do they have, do they lay all year or just once or twice? I have an old barn with a very large loft and I thought about putting the pigeons up their. Any info would be great!!
