Alright so here is our story from start to finish for those who might find the information helpfull. This isn't a guide, it's just how i did it on my first run along with a breakdown of costs and the results.
We raised 50 birds.
Weeks 0-2 the birds were fed medicated chick starter by dumor bought at
tractor supply for $22/bag.
After 2 bags of chick starter we moved them to a locally milled feed that is 18% protein and sold for just $11/bag. (I was worried about the lower protein content but a local guy recommended it and I thought we'd give it a try.)
The birds were turned out to pasture (chicken yard) as soon as they couldn't fit through my 2x4 woven wire fence and left on the 18% feed 24/7 for the duration of the grow. We tried a brief stint of 12/12 but I decided to move back to 27/7. I'll feed 24/7 moving forward. Perhaps the lower protein feed slowed growth just enough to avoid problems.
Around week 5 we started have a red tail hawk problem. I installed copious amounts of heavy test fishing line, built scarecrows, checked the coop constantly but none of this made a difference. The hawk would plunge through the line and was not deterred. We lost over a dozen birds to hawks who would eviscerate the chicken, eat the heads and usually leave the rest untouched. We actually ate a couple of hawk kills as the meat was untouched most of the time. We lost about a bird a day for 2 weeks and then the hawk went away. We never solved the problem but will install netting for our next batch of birds.
The first birds broke the 6 lb mark at week 7. We weighed them frequently to monitor growth. In general, my pastured birds on 18% feed were about 1 week behind the Cornish x growth chart. I attribute this to lower protein feed and the extreme heat we had this summer which left my birds panting and lounging in the shade for 10 hours per day.
We had no losses, other than hawks, after 2 weeks and ended up with 36 birds total. Most of our losses were hawks.
The birds went through 2 bags of medicated chick starter at $20/bag and 10 bags of unmediated 18% protein feed at $11/bag.
The feed bill totaled $150 which is extremely low considering they has access to feed 24/7. It's hard to put a per bird average since we lost several at weeks 5 and 6 but in the end we got 36 birds so the feed came in at 4.17/bird and would have been 3.10/bird without the dang hawks.
I am a huge proponent of cheap feed after this experience. I see no reason to buy top brand feed with higher protein content at this point. I'm not selling by the pound and a chicken, is a chicken for my family so any lost growth is inconsequential for me.
Feeding and watering supplies came to $90.
3-gallon waterer for the brooder $20
two 14 lb circular hanging feeders $15 each
a trough feeder $10 (this sucked, i wouldn't buy again)
gravity waterer with a recycled 50 gal barrel, some PVC and chicken nipples. $30
Total input cost to raise them (excluding enclosure): $240
Next post will cover butchering.
