Expansion for our critters

I began my business cleaning homes and small repairs. I worked a full time job and ran my business. I have 9 children and 7 grandchildren with one on the way. 6 of my children are adopted. Once Covid hit I was unable to do the same functions in my business. At home, we had raised different wildlife for ourselves and given them away. I decided I would move to making this morning full time and begin selling the animals. I currently have chickens, turkeys, ducks, goats, and now cattle. With each expansion I build areas for these animals. I incubate, hatch, and raise these babies so their “home areas” are important to me. 
I have one child and one grand child that is autistic and these animals are also therapeutic for them  I am looking now into expanding to a small petting zoo as well for therapeutic purposes. 
I am currently in need for larger incubators, more heaters for winter, and extending the home areas for these babies. I would also need the funding to build the area for the petting zoo. This is important to our family and any funding would be greatly appreciated.
