My son is 9 years old and in 4H. We are getting a trio of roller pigeons next week from another 4Her, and he has been really good about asking lots of questions of other pigeon owners, and I've been reading alot on here. BUT wondering if you all have any recommendations for a good "how to" pigeon book for him to read? Our local feed stores that have lots of books don't have anything on pigeons. Thanks!
