I only have 3 chickens. I keep their feed in a metal container. But the feed lasts a long time because there is only 3 chickens. I noticed last week the feed had soured. Not sure how long its been bad or how much they ate. They have gone about a week so far since they ate it. All seems fine. 2 Questions 1. Are there any long term issues they may have from eating this? 2.Can this make egg production slow or stop (or not start because they are about 20 weeks) THANK YOU!!!!
