I have just looked up the protein percentage on my feed and it is quite low :/ I will be changing when this bag is finished. Thanks as I hadn't thought of that. Will be worming at the end of the week! There is no draft in the coop but we have had some very cool nights! I have been closing the pop door and getting up early to open it to keep out the draught. I feed calcium and grit both separately due to a mixed age flock.
You almost need a degree to sort the feed dilemma out. The fact is that many of the feeds on the market don't ' come up to scratch ' , pardon the pun. Even those that do have the correct vitamins and minerals added lose their goodness after just 2 months storage and can also be affected by moisture and humidity.
I am regularly adding a vitamin /electrolyte supplement to the water now . I've come to the conclusion that can't always trust what is printed on the bag.
