there seem to be a few new GP owners like me about so am starting a list, please add your own
mine like broccoli (mainly the stalks), green beans, peppers, apple (sometimes), parsley (they LOVE this), cauli leaves, gem/romaine lettuce, they ate a whole bag of kale the first week then sniffed at the next bag and would not go near it (odd), they love grass, dandelion leaves and apple leaves/branches.
they don't like courgette, cucumber, tomato, grapes, rocket, corn on the cob, they eat some celery but not much, not keen on carrot either
what garden weeds/plants are safe for them to eat? I am sure I saw roses mentioned somewhere? we have loads of weeds but not sure if anything is dangerous to them.
