I have been very pleased with Myers as well. Ordered large layers before, and have chicks due in tomorrow. I am sure you will be pleased with them. If not, they will make it right for you.. Good luck....
Just ordered Gold Wyandottes from Meyers - Page 3

I used 1.5" couplers. They were $1.45 at Home Depot. The chicks took less than 5 minutes to figure them out. No waste, though they can't get to the feed below the bottom of the coupler right now, so I have to pour it out and then on top of new feed so it gets used up. I started them on these feeders at four days old.
