My exact thoughts. Any idea what they might be? They look like a type of bantam. Could they be a cross breed of the two?
To be fair the seller was an amateur who was just hatching eggs (something to do in lockdown) she did say she thought they were 3 girls. Oh well looks like I need 3 coopsYikes!! I'm thinking all are cockerels. ☹ Maybe Cochin Bantam mixes. That seller was certainly not being honest in any way, shape, or form!
