So my babies are 4 weeks old yesterday! We live within the city limits of San Diego, with canyons all around... and hawks are not uncommon. Is there some big plastic owl or something I can put on my roof to scare them away when I can safely let my girls out to free range? 2nd question, we normally feed backyard birds, finches, etc. but there's always a mess of thistle seed on the ground, I have read that wild birds can carry diseases not safe for chickens, also worried about the chickens eating the thistle seed on the ground. Any advice, expert friends? Lastly (for today) Have you had any incidents of your chickens falling into a pond? Our pond is small but the chickens would be able to find it. :-( Thank you so much in advance!
