As CityChicker says, there's not a lot of money in animal husbandry of any sort but you need to consider your current situation.
I'm not asking you divulge what your situation is, I think it's against forum rules but you need to consider...
What age you are, if you are young then try for an education that would allow you to go into the career you want, but would also be useful if you can't get the career you want. If you are older you might want to consider a more 'volunteer', part-time position. Sometimes employers don't always appreciate the breadth of knowledge, and stabilizing factor (like having a mom at work) older people can bring.
What your financial position is like, do you have someone who can support you through periods where you may not be earning much (or nothing). If you do then talk to them, see how they'd feel if you were not bringing home much money and/or working odd hours. If you don't have support then you really need to consider if the life you end up with would be sufficient to keep you happy. We don't all need houses with eight bedrooms and three cars and two month holidays in Bermuda, but we do all need something. Living in a slum is not conducive to a good life.
What if it all goes wrong, how easy would it be for you to get a job in the mainstream if you decide that you don't like your new job, if you are well qualified for something else then it might be worth a chance, if you have no qualifications then you need to think seriously about how easy you could get back into a position like the one you currently have.
Before taking the leap, consider working part time at a rescue shelter or national park, just at the weekends. Experience can often outweigh qualifications for some jobs you might apply for later.
I'm not a 'Follow your heart' person but I'm also not a 'squeeze the last dime out of my life' person, I'm a 'work hard for what you want but don't waste your life getting it' person. I have been fortunate enough and worked hard enough to have had a job I enjoyed so much I could almost have done it for nothing. I can't think of anything more saddening than working all of your life at a job you hate then retiring and only having a few years to actually enjoy the fruits of your labor. Work isn't supposed to be fun, else you wouldn't need to be paid to do it, but nor is it about getting the highest paid job you can and being miserable all the time.
Whatever you do, don't burn any bridges on your way out - you never know if you might need to cross them again one day in the future.
I wish you the best of luck with whatever you choose.
