Another idea is to sell their eggs, but what your family will consume, to offset the cost of feed and bedding. Most " Farm Fresh Eggs" go for about $3.00 a dozen and getting family and friends to save their egg cartons, will help with the cost of that also. We have quite a few locals selling eggs here for $3.00 a dozen, so I just priced mine at $2,50.
If I sell 6 dozen a week, from my 14 pullets, I still have 2 dozen a week left. More than I need, so I can even give a neighbor or family a dozen. That covers my feed, gas for car, and bedding and a little extra in the cookie jar for a few other things.
The biggest con I for me, is the added expense of feed, in the winter, as I live in a far northern climate and this year, winter hit early and was very cold. The birds ate way more than they would've in a normal winter.
Another way to offset costs is to save the egg shells instead of buying oyster shells...I just crush them up and add them, UNDER, some wetted layer pellets, and no egg eating here, as they gobble it up so fast, they have no idea they just ate the shells
I have found that 14 pullets, almost hens now, is just the right amount of birds to become a self sustaining flock.
I have a poop board, and clean it every morning, I use pine shavings and some straw, and no smell, to speak of. Takes all of 2 minutes to scrape off with a putty knife and sump in the compost pile. MOST of their poop is on the poop board...very little in the bedding. I also add some scratch, especially in the winter and that keeps the bedding so well turned, any poop in it, is very quickly dried up.
