Goat is VERY strong, needs lots of spice imho - big market for Latino buyers (they love it). You could sell or trade it.
Hey mygirls, pls don't post a pic of the fox (when dead) unless you are very SURE you killed it legally, or some nut may sic the law on you. If you only say you killed it, you can say later you lied cuz you didn want to disappoint people here - but a pic would be hard to explain away. Not sure if you could be traced or if they'd bother on a fox.. In general, make sure you follow the laws,anyway. You are 99% likely to be okay here - but don't make trouble for yourself. Remember, the internet opens you up yo all kinds of crazy people.
Wish we could have goats - zoning only allows chickens.
RIR & rocks are good birds - if you can get $25 for a laying hen, that's good. Consider a RIR roo & a few more RIR hens, as pure chicks may sell better - or go rock roo.. Now try to figure if you can sell "a hen about to start laying" - as young as you can get away with. That way your feed cost is as low as possible, and the buyer knows they'll get full useful life of the bird, even if they have to wait a few weeks or months for eggs. That's how you make it sound like a great deal. No way the buyer is getting ripped off by an older hen. It mightwork.
We're in a city - lots of people here like fancy breeds.
Cheese is not hard to make. Some is tricky tho with many steps & an aging time, like cheddar. Other, like mozzarella, is ready right away. You may have to do a few batches to "get" the process. Main problem for us is poor curd formation, cuz of store milk - heat pasteurization can harm the curd protein. Much easier to get curd with raw milk.. Just make sure it's good milk - that you clean udders and so on. Read up on safety w/ raw milk cheese (of course you know that).
Oh, as to predator questions - something will replace the fox, yes, & go after birds. Sometimes shooting coyotes, they say, causes bigger litters or more breeding females - and even MORE coyotes later.. Who knows. Killing a bold fox is important, but a good strong fence &coop is main defense, as has been said.
