I have extremely picky girls that only eat grapes for treats! What are some treats y'all feed picky chickens? (I didn't know they existed!)
Chickens will eat a wide variety of things but are nervous about new things. Try stopping the grapes and just leave a small pile of bird seed or scratch in the run and ignore it. They will watch it for a while but sooner or later one of the girls will get brave and try it then the others will follow suite Just be aware that with treats they will need grit. I use construction sand for grit and it works well and is cheap. Its the same sand you use for mixing concrete and you get 50lbs for about 4 bucks.
As far as training them just call them and give them scratch in the run only and they will go into the run by themselves. As far as other treats go you can introduce other things to them over time it will just take time for them to get used to new things. Just remember treats should not be over 10% of their diet

Mine are 4 months old and are absolutely crazy for spaghetti. I can get them to do tricks for it already. But that's mainly for my entertainment. To help beat the heat in Florida, I put out slices of frozen watermelon for them. The love it. As for when to de-worm them, I sprinkle Diatomaceous Earth in their food and their bedding to help with internal and external parasites naturally.
