My hen hatched 8 beautiful chics in the coop. Our coop floor is sand. I’m worried the babies might be eating the sand? All their crops seem super full & now that I’m thinking about it I’m not sure I see a lot of baby chic poo. Would they eat the sand? And if so, would it hurt them? What can I do? I was thinking of taking the mom and chics into a dog cage just to keep an eye but maybe I’m over reacting. Any advice appreciated!
