I am not familiar with Mauve, other than knowing people often breed Mauve while they also breed Chocolates & Lav lol. So I cannot ID him as I haven't really worked with or seen many, but genetically it appears they'd be a Chocolate/Blue mix (similar to Lilac in dogs). In which case:
Mauve +...
It didn't show the pic with the chicks, they certainly aren't all black so there's definitely some other hens or genes your boy carries! Barring is obvious, I would assume the barring is sex linked from your hen, not him. I believe the pattern on his neck is something different but I can't...
he just looks like a poor quality lavender to me, with leakage, plus maybe some extra corn ;D my lavender get a "corn necklace" we call it lol
Lav + Barred Black = black pullets, black barred cockerels
Lav + choc = black chicks, carrying choc + lav
Lav + SLW = black chicks, carrying lav +...
Behaviorally that matches my buttercup I had! The markings seemed a bit off but they have a very obvious comb. I was suspicious of BC but didn't hear back about what combs they had. I would be surprised if #1 was a buttercup with those markings but time will tell!
I'm no wyandotte master but I'm getting boy vibes. I looked through this which has nice side-by-sides, I feel like yours is a little column A a little column B, I'd give it some extra time but I wouldn't count it pullet just yet personally (and maybe be pleasantly surprised later!)...
In my experience we saw way more "poor blacks" ie a black with just not great color to it, weak, than we saw really dark blues. Maybe it's just some breeders preference for a bird who looks distinctly blue so that's what ended up common over here, but typically it was poor black not dark blue
I work at an animal shelter and I always gotta tell people that these dogs are not DNA tested, they are visually IDd to a close visual match but the only thing we can guarantee is it's 100% dog 🤣
So I don't know why they do it but our hens always were upset at the broodies unless it was top hen, in which case that hen would just kick the hell out of them. The way we'd fix it was well to break the broody. We didn't have any problem roosters, it was just the flock said "no" to that hen...
I would guess something else, he's got clean legs. But without knowing if he's from a hatchery/feedstore or someones backyard mix it's hard to say for sure (doesn't help he's a fairly average red/black color vs say a crele thats easy to ID 🤣)
My neighborhood is routinely a warzone around the 4th. We had fireworks starting on the 31st of June and they're still happening daily & nightly. On the 4th they began lighting them off at 11am and didn't stop until 3:30am-3:45am was the last time I heard one (the dogs won't let me sleep until...
I believe they start about mid way down the back, but I'd check higher up if you're unsure just in case. Iirc they should start mid way up the back and eventually be long enough to flow off the body in the classic saddle shape
She's just an easter egger :) they're like "doodles" they have a pretty classic look but some variation in size & color, and while are kind of a mixed breed, they're kind of their own thing. There is no chicken DNA tests widely available and likely her parents looked like her and their parents...
Oh no hmm... it's a bit hard to tell in the lighting here, do they all have saddle feathers? Skinny, shiny feathers around the area where back meets tail (may also see these skinny shiny feathers around the neck). These feathers look different on teenage females/pullets they'll remain round...
I would check underneath the poof, I would expect to see them in by 15-16 weeks for sure, here's some of new feathers that haven't formed a "true saddle" yet
