I tried the FF, too, but these from Meyers seem to be growing very sloooowly! Mine are 4 weeks old today and very necked looking. I feed half ff and half wet food. I do not see any difference in size. I was told with ff to reduce the protein to 19% rather than 22%. I am going to the feed store tomorrow and up the protein. I have gone through 150# of feed so far for 50 meaties, but lost 8 over the last 2 nights, due to not enough feathering and cold nights in the high 30's!My 18 meaties are 6 weeks old today I will be butchering the weekend after thanksgiving I grabbed two at random and weighted them today one was at 5.6lbs and one was at 4.9lbs and they werent the big ones so for doing this my first time I think Im doing not to bad. I had them in the brooder for 3.5 weeks till feathered there they eat through one bag of chick feed and some of a bag of flock feed they finished when they moved outside to an 8 by 4 tractor. We found a local brewery and we get barley mash one 35 gallon trash can full for $10 also got grain 80llbs for $12. I take the grain and soak in apple vinager and water and serve them that and the barley mash and move the tractor once a day the meaties still seem more active than everyone told me they would be but they are getting big. They get veggie scraps from the garden. I am about a 1/3 of the way into the one can of barley mash and thats feeding it to all 45 of my birds birds.
1 bag chick start $13.99
1 bag flock raiser $13.99
1 35 gallon barley mash $10
1 80lb grain $12
= 49.98 to raise 18 meat birds

BTW, did you forget the price of the chicks and the ACV in your costs? In 2 weeks mine won't be ready for processing as I was sent all females and they take longer, but I will total up everything and get back to ya'll. 3+ bags of feed @ $14.= $42.plus ACV@$4.plus 1/3 sack of grain=$4. plus 1/5 sack of oats= $3., chicks and shipping $63. comes to approx. $116./42 chicks left so far or about $2.76 per bird so far.at 4 weeks old.
