Happy 2015! I have been browsing old posts (2011 etc) learned quite a bit...I had no idea avocados were bad for chickens and however, did know mealy worms can be overdone, they belong in the 'treats' column. The reason I came on board this morning is for the question of cracked corn in scratch. My flock (29-30) never cleans it up, they eat all the other grain, even the mice, pack rats etc. won't eat it!....I suspect the feed purveyor is 'off-loading his surplus corn...anyone else have that feeling? As to lay-crumbles, our 'meter-reader' for our local electric co. raises all his meat from goats to chickens....he taught me to make a fairly thick mash, like your would for ducks, out of the crumbles....the chickens truly love this. According to the size of your flock and in the mornings, in my case....1 1/2 medium scoops of lay-crumble and just enough water to make a thick mash in approx: an 5" deep x 20"wide rubber barnyard dish....trial and error. If your gang hasn't cleaned this up by the end of the day, you're making too much. Have a wonderful New Year!
