Hi Sally. Don't advise you put corn in with the pellets as they will throw the pellets out to get to the corn. Just give them a very small amount unmedicated scattered anyway, several times a day to break the boredom. Ours go nuts in the runs for 7 days but without it they don't worm properly. I intend to mix flubenvet with cod liver oill next time and give them all a shot of it as they get let out (2 person job). A scoop of Flubenvet treats 2 kg of feed, which is enough for two large fowl chickens for 7 days. If the oil added to Flubenvet measure makes a thin paste of say 2.1mL, each bird needs 0.15 mL a day. I've done it as an emergency worming of a sick cockerel who wasn't eating (Claude, my avatar) and it worked a treat. He noticably improved after the first dose!
