My hens have not missed a day in a week knock on wood.... I have feed soy free from day one and switched to green mountain soy free layer pellets once laying.
Mine are 15 weeks old and haven't started laying - I just bought this bag of GM soy-free to have on hand and start mixing with their grower feed - I have a sex-link that is getting bright red comb/wattles and is squatting so I think she may be an early
Mine started laying shortly...
I called the feed store and had them check the tag on the green mountain soy free layer it is 16 percent protein and has fishmeal. The website for GM must be out of date doesent list fishmeal and says 15 percent. I wonder why they don't put sunflower meal into the feed.
I am feeding countryside organics and have four hens almost five months old. One has started to lay and has only missed one day out of eight days. I just started to feed BOSS today to see if it changes anything.
