Hi Nancy, I'm sort of doing both....jumping in feet first that is...I decided that I would start my first year with meat birds and then see if I liked it well enough to add layers. I have a neighbor who does meat birds, so first year, he is buying the birds, feed, etc and we will raise them. We are providing the housing at our expense.
At the end of the "season", he will have the birds butchered (commercial butcher who also handles small producers). We will then sell enough birds to break even on his investment and split the number of birds we have left over.
We are starting with 25 birds and expect to have 5 chickens in the freezer for each household.
The meat birds only have to raised for about 3 months so we can see how we like raising the birds.
It's kind of a nice way to get started with minimal investment. At the end, we only have the investment in housing and feeders so if we change our minds, we can re-purpose the housing and will only be out the expense of feeders/waterers, etc.
I'd say nothing ventured, nothing gained. Go for it! I have a feeling I'll be doing this again next year!
