Hello, I have a suspect that the new brand of feed I bought is of poor quality. I have some laying hens, that were on a feed store feed before, that costed the equivalent of 22 USD per 30kg (66lb) bag. They were laying fine. 16.5% protein, all minerals (basically the usual recipe of grains, soya, and minerals). Then i found another supplier, that sold 20kg (44lb) for about 10-11 usd, the brand name seemed nice, they even wrote what kind of GMO soya it was and origin of ingredients.. and what happened? well. Within a week or so, egg production dropped significantly and it has been low since. I didn't think much about it, then I figured that I have a "control subject". I have a cornish cross hen that we keep as pet, she is 1 year old, and had been fed 50% the old feed, 50% wheat, as she wasn't laying for a long time. Well. She started laying again in spring. whereas the other stopped. The only note is that the new feed was 2 months old. the formula of the feed written on the label is pretty much the same of the other feed, but what is written does not guarantee that they did put in what's written on. the egg production drop feels a lot like depleting nutrients in the hens to me. Any thoughts?
