Just joined this thread as I'm trying to figure out which cuckoo marans are girls or boys. They all have dots but one looks for sure like a girl and another one looks kinda silver-ish so I'm thinking it's a boy...but here is a pic maybe some knowledgeable people out there could help me with this?yes, some cuckoos will appear more silver in tone as well. The larger dots are usually your roos indeed on the cuckoos
