GlennLee-
I only started experimenting with fermenting a couple of weeks ago and I have mixed feelings about it. It is a bit more work than just dumping feed in the feeders, but the birds seem to like (not love) it. I think I need to tweak my method and the food I am using. Right now I have a bag of Nutrena Meat Bird crumble that I am using. It is very fine crumble like chick starter so a lot of powder. If I put that straight in the feeder I know a good deal gets wasted. In addition, I don't know how they chomp down on mouthfuls of dry powder without needing a drink after each bite! It does cake up on the edges of the beaks too, especially my turkeys. So there goes more waste. So...
For fermenting, right now I am using three half-gallon jars. Those are the biggest I could find at the time and the amount of food I can do in them is fine for breakfast but I could certainly use more room for expansion because the food goes right up to the rim. I fill the jar about halfway primarily with the crumble but I like to mix a small amount of scratch into it as well. I then add warm or hot water almost filling the jar, wait a bit for it to expand, and then add more water. Its hard to find that right balance between just enough water so it is moist through and through and not having it come out soupy when I try to serve it. Anyway, each day after I feed I refill the jar in this manner and it goes to the end of the line (of three jars). So, a jar that I fill on Monday won't be fed until Thursday. The jars that I am using are mason jars with the two piece lid, so I don't use the center section and I cover it with a coffee filter and then put the ring part of the lid on (I hope that makes sense). Fermentation is anaerobic, so you don't need air to be able to get in, but you do need the gases produced by the fermentation to be able to get out or you risk an explosion. And of course the filter helps keep bugs out. Still, it is attracting fruit flies so that is something I need to figure out. I think bigger containers will solve that because right now when it expands sometimes some of the "juice" gets wicked into the coffee filter and that is what is attracting them.
Some people use buckets - either a series of them or just one. Using just one seems nice. Basically they ladle out however much food they need and then add back in some dry food and water and stir it all up. The only issue I have with this is, the next time you feed they won't get all fermented food (some will be the new food you added the day prior) and it would be hard to ensure a good exchange of feed so you don't leave any in there too long, because it will go bad. I still have almost a full bag of the meat bird crumbles so I'll keep going with it at least to the end of the bag.
For feeding the fermented feed, you are only supposed to give them as much as they'll eat in about an hour. I ladle mine out into 7 plastic take way trays saved from a local Chinese food place. That lets me put down enough feeding stations that everyone gets fed without a lot of fighting and bullying. If I keep going with it, I might try to make a sort of trough system I could just pour it into. The other change I would like to make is to switch from crumble to grains but I can't find any local mills that sell or make small batches of poultry rations. I have been looking for information online for how to make my own and I plan to go to another feed store that sells lots of different grains and figure out what that would cost me. I want to make sure I can come up with something nutritious for the birds but easier on the wallet, especially with winter coming up.
Last week I went to a different feed store instead of
TSC because I wanted to see what their prices are. They are a Southern States store so the feed is made somewhat locally (PA). I think they work sort of like a franchise and use local stores and feed mills, so price will vary by location and day, depending on grain prices. Anyway, I was able to get 50# of 20% Meat Bird Pellets for $13, which was a good deal, and I'd been wanting to try pellets with the birds to see what they thought. The turkeys loved it. I think it is more satisfying to eat than the mouthfuls of dusty crumble. The younger birds (including the 5-week old keets) also really like them. The smaller birds just pick through to find broken smaller pellets for now, but they don't toss the bigger ones on the ground. The only ones not on board are the oldest guineas. They don't want anything but dry crumble. I'm going to stop catering to them, though, especially now that there are only two, once their baby is old enough for the pellets. Anyway, the pellets go into my big feeder and I put that away at night into a large trashcan, and I put it out in the late afternoon if they are free-ranging all day. Right now it is rainy and dreary so everyone is staying in the run, so I need to put the feeders out earlier, but I don't endlessly fill them because I think like people they will eat out of boredom as well as true hunger. I go out every now and again and toss them some scraps or birdseed (I'm out of scratch right now). My scraps consist of almost anything leftover from cooking or cleaning out the refrigerator, including meat, vegetables, grains, bread, you name it. I have bought them a watermelon when its hot, and I will probably buy them a pumpkin before long.
