Tragedy this morning! I went out to feed the birds and found one of my Delaware pullets upside down and dead in the 4" tube feeder. Apparently the feeder was empty or close to it and she was trying to reach down and got stuck. They are just 3 months old now and her body was just the size of the feeder. So sad. This is the tube feeder design on BYC using the "Y" fitting. If anybody else is using that style, beware, hazard for young birds if they get empty. Now I only have 4 pullets and one looks like it has the Columbian pattern.
