This might seem like a silly question. But can you tell the sex of your ducklings by weight? I weighed my 3 mallard ducklings and one weighs more than the other two. Pink- 2.8 oz purple - 3.0 oz and the unmarked (rascal) weighed 3.5 oz. seems like a high jump from the other two. Thank you 

Hens go broody when you don’t want them to… and won’t go broody when you do.
