Hello. I have a four month old bantam frizzle that I am beginning to suspect is a cockerel. These are my first chickens and this is my only frizzle so I have no one to compare her (him?) to, and it seems hard to tell with frizzles. She has started kind of crowing in the morning, not a full on crow but seems like she's trying to make the sound. She's a little bit of a bully with the other chickens and I've seen her chest bump them. I'm attaching some pictures from today and one of when we got her at 4 weeks old. Thank you for taking a look!
P.S. I know their waterer is sitting low, I was just letting them free range today and took it out of their pen and set it on a empty pot while they were running around.
That definitely looks like a cockerel, and the behavior matches up as well.
