I just wonder if the hatch date is right. These just look like younger cockerels to me. But they could be late developers. I don't see them being pullets, in any case.
The first one could be a cockerel with its comb and wattles being larger and more colorful. I'm not 100% confident, though.
With the other, look to the comb and wattles. If they are small at this stage then you probably have a female.
2 is in between. Its comb is red but not that big. The coloring is mixed. IDK, I would give that one more time.
You can re-home cockerels at any time. I think the sooner the better, if you can find people who will take them. Posting on Craigslist is one option. Hormones come in when they come...
1, 6 and 7 are definitely males. I suspect 2 is also male but not definite at this stage.
The rest are looking like females to me. 3 is definitely a female.
A hatch date of April 13th would make them over 5 months old. I think they must be females if that is the case.
Edit- No, I change my mind. I think they are both late blooming cockerels. Final answer :)
Sometimes they peck because they are scared or angry, and that usually hurts a lot.
When they peck gently it is either they think your fingers are food or they're mildly annoyed and want to be let down.
That's the way I figure it, anyway.
Maybe Golden 500 or Gold Star? I've seen both hybrids with males like that. I'll post a picture of Gold Stars from MCMurray Hatchery's website.
For gender, I can't help. I've always waited until they were old enough for the quack test.
He is a Sicilian buttercup. They are slightly larger than Leghorns, so not big. He is not thriving if he is only a half pound at that age, but I don't think he is a bantam. With TLC he might improve or might not.
The bottom picture shows Belgian bantams in a few different colors. Also known as D'Anvers.
The top picture might show Swedish Flower Hens. They can be crested.
If the red one is from a hatchery or feed store then it must be a red sex link pullet, despite the massive comb and wattles at such an early age. However, if it is from a backyard flock then it could well be a cockerel.
The comb looks pretty big for 11 weeks. I think it is a cockerel. If it is, male specific feathering should start coming in withing a few weeks, and that will confirm gender.
Yes. I'm not sure which edition that one is. I found an older one at Goodwill for around 10 bucks not long ago, and I have a version from the 80s as well that I used when I used to show chickens.
