Does this specific recipe look good to you? I found it on Youtube.
- 20 lbs Whole Oats
- 20 lbs Black Oil Sunflower Seeds
- 10 lbs Flax Seeds
- 10 lbs Split Peas
- 5 lbs Sesame Seeds
No.
After correcting for water content, its about 16% CP - fine. And in meets the NRC minimum recommends for adult layers for Met, Lys, Thre, Tryp. IN THEORY.
In practice, there is a crazy amount of fiber in that (around 12%) which isn't the benefit to chickens that it is to us human types, and there is an extreme amount of fat in that (around 25%).
If you had to get birds thru a week or two w/o regular feed, sure, its not going to kill them. Its not even the worst "make at home" recipe I've seen. Longer term,
I would not recommend. Besides not being remotely cost effective, the beta glucans in the oats, together with the generally high fiber level throughout, will adversely impact nutrient uptake - the feed is of lower value than calculations suggest. High fat, in addition to representing an excess of dietary energy, also promotes rancidity - use it quick. If your flock size is big enough, not an issue. Some of the other seeds, depending on processing (I'm looking at you flax!) may not be effectively used by the birds, either.
I've not looked at all at the Vitamins, my calculator doesn't figure those, but you have essentially no non-phytate (that is, not plant-based) phosphorus. Since the Ca : P balance is critical fora lot of bodily functions (almost everything otherthan eggshell production), even if you are offering free choice calcium, the birds likely aren't getting the Phos they need to make effective use of the Calcium.
Sure, the grounds you are free ranging on *may* mitigate some of those concerns. But without testing, you can't know.
Personally, I'd categorize that as high quality (and high price) scratch.
Since I can get 50# of commercial feed for my birds of known (and superior) nutritional quality for less than the price of the 5# of flax in the above recipe, I'm definitely steering clear.
