You have come to the right place, there are a lot of very good people here.
As for predictors, you have a verity of hawks (Harris Hawk like to work in teams), eagles (usually passing thru seen 1 golden and 3 immature or golden eagles in 27 years), horned owls, coyotes, cats (domestic, bob cats and cougars), skunk, a very few raccoons & possums (imports and very rare as yet), and of course dogs. We have scorpions that are on the chickens menu but once in a blue moon one dose get stung. Chicken in on everyone's menu. Ferrets are not an issue, a few are out there that have escaped, I have seen them, but as of yet do not know of any attacks on chickens. Anyone wish to add to list? I am pretty num to things going on around me, but I tend to see animals.
Summer heat is the biggest problem. I gave my girls corn as a treat, bad idea here. They got fat, very fat. They do not need corn to keep body temp up as in cold country. If you were West Washington you had mild winters. If high up or east of the mountains cold winters and higher calorie winter feed. I was very stupid by giving them corn.
Also many of use purchases organic feed (non-soy) from Big Sky. It is delivered every 2 months. We usually will help each other out by taking turns picking up for our neighbors that live close to us sense we are all over the state.
[email protected] is the coordinator of the feed.
One last thing as you are about to inter into chickens you must be made aware of the dangers:
If you still want chickens good luck and happy to hear from you.
