I haven't purchased any ducks, we're waiting to finish our chicken coop before we start a new venture... however I'm concerned about Bald Eagles. We have 2 that we see almost daily, as well as random hawks and buzzards. Any special precautions I should take? My husbands wants to put a few sunken kiddy pools around for them, and I think he wants to put them with the chickens? Any advice? Thanks!
