I bought “call duck eggs” off of eBay and currently have one of the ducklings from that hatch. She is almost a month old and since about the first week I’ve been questioning if she’s really a call. The person I bought them from claimed he only had call ducks but my duckling is currently huge. The egg she hatched from was quite small, like chicken size or smaller, and it weighed 40g, so maybe she’s a mix? This is her just hatched, a few days old, 3 weeks old, and next to one of my week old Pekins. She weighed 359g on Saturday (3 weeks and 1 day).
