im looking for some advice on caring for ex battery hens. mid december we are going to 'rescue' around 200 from 'factory' here in Belgium and will be keeping around 25 then finding homes for the rest. im basically looking for any tips on how to care for them? im guessing they'll need a little extra TLC..... its gonna be cold here mid december and they'll be coming out of a heated hangar into possibly freezing temps..how is that going to affect them? what do battery chickens eat in there?
