Hi all. I'm not too new to caring for birds (I have a pair of chukar partridges), but I am new to pigeons. I am picking up 6-8 racing homer squeakers in about a week (I think my loft size will be maxed out at 12-15 birds). They come from very good racing lines. I have my loft all built, just need to put the aviary on the side and build some perches on the inside (nest boxes are done). I have a few questions though, and was hoping for some insight: How long before I can let my pigeons out to fly? I hear 2-4 weeks, and was going to play it safe and wait 4. I plan on first starting to train them to use the bob one-way door, so they know how to get back in before I fly them. How do you guys feed the grit--do you mix it into their food, or do you put it in a separate container? Also, I plan on feeding only the amount of food they can eat in a day so as to be able to fly them hungry and properly train them--but do I need to do the same with the grit, or can I just load up a feeder full of grit and only refill it when it gets low? Do I need to give them crushed oyster now, or only when I start seeing them lay eggs? Any other pointers you guys can think of that you'd like to pass along, I'd greatly appreciate it! Thanks!
