At 4 months by the look of their combs & feathering (from what I can see) they look to be pullets. Could you post pictures of them standing on their own, top & sides?
Jeez Im hitting gold with pullets Thankgoodness it was strictly roos until now. Yes, i will post photos of them from different angles. They are so cute!
Lovely little ladies all around! At four months, a cockerel, should have at least a hint of red in the comb - and even if the lighting is too bright, both appear very pale.
Lucky duck!
