I have the Grandpa feeder. Have used it on and off for 5 years now. Wish I just left it when I first had my chickens using it - was great. Now I need to be using it again due to rats (of course). I have 2 original 5 year olds that know how to use it. "they say" the other chickens will watch and learn. So how long does that take? I have 3 others (2 hens, 1 rooster) that do not understand. I will say its only been 2 days I just feel bad when I go in there and my Weezie stares at me like, "wheres my food?" I see the older ones stepping on the treadle and eating, and she might go and grab the food but they are bullies towards her. I push the treadle for her to show her, she steps on it and eats but then she steps away and doesn't understand.
Hens go broody when you don’t want them to… and won’t go broody when you do.
