I have a week exactly before weigh-in. The chickens are all weighing 6lbs. 8oz roughly. Some a little more. Our weight limit is 7 pounds. SIGH. I have been giving them scratch grain instead of their usual 20% protein mash for a week before last week I saw them were getting to heavy to fast. Ive weighed them everyday for 9 days.. they are gaining usually 2 oz. a day some more depending on how much they ate that day. Today I started to run them around the barn to get them to maybe loose a few ounces and strengthen their sad not so meaty legs. Any suggestions on what I can do different to keep them from gaining anymore or possible get them a little bit more in a comfort zone of 6.5 in a week?
