I ordered some pills to give my chickens to get rid of tapeworms. The dosage would be half a pill for my smaller ladies and one pill for my big guys. Turns out this pill is actually a capsule! So it has a casing that can be opened and powder inside. How on earth should I administer this to everyone with the proper dosage? I paid $40 for this medicine so I don't want to have to buy something else. Any ideas?
