hi i recently got a 10kg of marrages pellets with wormer in for 6 large fowl and 5 bantams. i thort it would easily be enough the to last the week but its only lasted to day 5. we have rats in the garden and have bait down in a bait station to try and get rid of the horribe scavengers so i assume they have been eating the pellets for the hens as well. will the wormer will have worked. it says give them for 7 days but if i re order another it wont get here till tues nxt week. not happy about it but nothing i can do what do you guys think thanks x
