I have week old chicks (6) in with a hen that has adopted them. All look well (chicks and hen). Hen just pooed - and white worms came out. Do I need to move her from the chicks? Is it ok to treat with a dewormer - or are the chicks too young for treatment? I have been keeping the area really clean - changing paper towels on top of pine shavings every few hours....Appreciate any help.
