Let's see....we usually go to the Everett Co-op or to the Bothell Feed Store. Prices are about same..not too different really.
#50 of game bird 20% crumbles <for their winter treats> and it was about $18.00.
#50 layer pellets for about $14.00 (Purina Sunfresh non organic)
#25 BOSS for about 15.00
2 poultry flock blocks <for emergency winter lock up> @13.00 each. (Yes I know I can make my own and will start doing that...atm it was not feasable)
2 bales of white shavings are about $8.00 each
We get 1 bag of oystershell...lasts forever so we just get when needed
We get 1 lg bag of grit....lasts forever so we just get when needed
The pellets last about a month or so. Its all free feed, we have a 12 lb feeder that they use. I refill totally about 1x a week...but add to it as needed during the week. We also make sure that we have an extra bag on hand in the fall/winter/early spring...in case we get snowed in like last year. 2 1/2 feet of snow here last year.....we couldnt get out of the house!!! We never had it so much since we moved here 10 years ago.
In the winter, I give the higher protien game bird crumbles as treats, and use for hot breakfast for them. They last about 4-8 weeks, depending on the appetites of the girls. I wanted to make sure they have extra protein in the winter, so I suppliment the feed with the crumbles. This is mostly used during the winter/early spring when it is so cold here, so that is only time we get it. If they are molting we get a small bag as treats.
The BOSS lasts a bit of time, a good few weeks at least, so like 4-8 weeks. Its mixed in with the feed and given as treats in the bedding to promote turning it...not a lot tho.
The flock blocks I get cos here in the PNW it gets rainy in the late fall/winter and thru till spring. And icy. And snowy....generally nasty at times where we are, so we know they will be coopbound for at least a few days to a week or two. ATM its easiest for us to buy it but we are planning next year to make our own.
The shavings we get every other month. We take some of the old bedding out and place it on the dropping board. When we clean off the board, we add to the floor bedding, and add more of the old bedding to the dropping board so its constantly being cleaned and rotated.
So really, the only thing we buy on a regular basis are the layer pellets (monthly) and the BOSS and bales of the white shavings (bimonthly). The girls get treats of veggies and leftovers... I save my greens, veggies and meat scraps for them, as well as bread heels etc. So they have a very well rounded diet. And of course if they can get in the run, they have bugs and such there.
