I believe you're correct, Trish; a mottled carrier can show the odd white marking, but I would expect more in a true mottled bird, even with low expression.
With that said, there are other possible reasons for the white; a cock in his eclipse can also show white, or it could be silver leakage.
Tenancy and pets is always iffy, but I agree that a dog is far more disruptive than a couple of hens. Has she had a word with the council regarding the situation? As she was already a tenant and already had the two hens before this person took over, could she be grandfathered in, and at least...
How are Speckle's doing? Hopefully the weather does turn up; I imagine your living room is getting full! Has she started to be nicer to Millie yet?
I've had to put one of the runs I took down for reloation before winter back up where it came from for the 20 older chicks to go into. Still stood...
9 from mine; turns out she had 10 eggs, not 8, though no idea if that was my doing or hers. Pleased, nonetheless.
I've been selling an awful lot of hatching eggs recently; seems spring is here, just not insofar as the weather is concerned. Anyone else seen floods? The detour I have been using...
Sorry to hear about Matilda, @PouleChick. There's not much can be done about reproductive problems; @CCUK said it all, but very young, poor girl.
Lovely chicks @CCUK, Speckle will do well, I'm sure. Best of luck with your eggs too, @MSirrell91. Judy's 8 are due Monday, and she's sat tight.
She's very striking with the contrast from her orange eyes to her black plumage. If it is a separate mutation, that would be exciting, but if it is a lack of melanisers, she could lower the standard of your sumatra line long term.
Assuming I am correct regarding her genetics; As melanisers are...
I'd be interested to see the bird in question. My concern would be that light eyes would generally denote a lack of the melanising genes necessary for a true black; a pullet without them may not show leakage but a cockerel often will.
@Cyprus has shared some fantastic resources, my favourites too. Here's a couple more for your interest:

The only difference between the two varieties is that buff Sussex are gold, light silver. Silver is dominant, and is sex-linked; while males have two loci for the gene, females have only one. With that in mind, a cockerel may be silver, gold, or both, like your bird, however hens may only ever...
True, though from the mother she will have received a gene for a second e-series, presumably wheaten. The red will show through; the throat in particular has that tinge.
She's a lovely bird, though, and ought to lay nice big green eggs. I have several from a similar cross; Lav Araucana over RSL.
White Silkies are usually recessive white, though I've heard of paint birds making their way into a white pen. It's always interesting to breed recessive white birds as there could be anything underneath. My white cockerel is gold/silver split duckwing, and he's also blue, which was a nice surprise.
Is that with recessive white, @Mofarmgirl? I believe the only tangible difference would be in the chick down, as recessive white is very powerful at pushing out pheomelanin, but then so is silver. If you are seeing more silver males from the group, it would indicate sex-linkage at play, so...
Leghorns are unusual in that their white variety is dom; it is not as effective at diluting eumelanin, and has little effect on pheomelanin, so ismore useful when breeding for white and red/gold patterns.
Most all white varieties are Recessive white; it covers all sins. With that said, a bird...
White leghorn are Dominant white, as are any Pyle variety. Paint birds are single factor dominant white.
Dominant White dilutes eumelanin (black pigment) to white, with only a minor effect on pheomelanin (gold pigment). It is incomplete dominant, so a bird with a single copy of the gene will...
Yes; that's little scabs from pecking damage; it's normal for birds to peck if a bird lower than her steps out of line, but unusual for birds to actively seek out and bully others. Some start to develop this kind of dominance behaviour when they can't get out foraging and roaming. With my lot...
Funny you mention the self-white. I had some end-of-lay hens from an egg-farm once that were just that. I had thought them extended black dom white at first, but they bred as silver Colombian wheaten with dom white. I thought it strange that they were there at all, honestly, as various forms of...
@nicalandia, thank you for the pdf there; interesting reading. I understand that RIR, like any self-buff or red bird must have something other than Co restricting black pigment, but what could darken the pheomelanin but Mh? Ginger is a restrictor, like Co, with little effect on the depth of tone...
Whilst Mh is a dominant gene, I agree with @sylviethecochin that there are very slight phenotypical differences between a bird pure for the gene and one impure for it. They'll both be red, sure, but a double-factor bird is going to have a darker tone by virtue of the extra dose of Mh, though it...
Just rusty. The sex-linkage still stands. A female may only be chocolate or not, she has only one slot for the gene. A male may be pure or impure for chocolate, therefore he can hide the gene.
Chocolate over Splash hens would produce mauve pullets and blue split cockerels, hiding but not...
