so I have pulleys that are 15 weeks old and I have a crew of meat birds that are 2 weeks old. I am running out of food and local tractor supply had organic meat bird feed for half off. Expiration date in 4 months. My question is can I feed both crews with the same feed? The only thing different I saw was the protein levels were at 22% versus the 18% I have now. Is it ok to feed the?
