I was using Dumor which I was getting at TSC, and it was roughly $14 for a 50 lb bag. I stopped in Big R the other day and was stunned to see the Nutrena layer food was $7.49 for a 40 lb bag, so I bought that and brought it home and gave it to my birds. First thing I noticed is that my birds are eating it a lot slower. I'm not sure if that's a good thing. They are in the early stages of egg laying, so they aren't laying regularly, but they are still laying. I give them oyster shells and whatever table scraps we have so by no means are they starving! But they are just not eating it as fast. I am wondering if it's a good feed, does anyone else use it? Cost was a big reason why I switched. I can get two bags of the Nutrena for the cost of one bag of Dumor. I am comparing the two to see if I should stick with the Nutrena or should I go back to the Dumor. Any advice I get would be much appreciated. Thanks for reading my post! ***Edited to add that while on Dumor my birds were plowing through a 50 lb bag in about 7 days time, sometimes less time than that. They just devoured it. With this Nutrena it takes the 42 birds about 2 1/2 days to finish off a seven lb feeder full. It's easier on my budget, that's for sure, but I care more about the health of my birds.
