I am new to this and have two chicks. I am going organic with these ladies and am only going to be eating their eggs. Do I need to give them any sort of medication for de-worming later? I havent heard anything bout it and just wondered if it was part of owning chickens. does Food grade DE do that? I just was wondering. Can someone let me know. thanks! Ps: I dont think they have worms or anything..I jsut want to know what to do for the future. I have them on a non medicated starter still.
