SF or DF ?

[immortal]

Hi all. I'm writing you from Turkey. I have some questions if you don't mind. I can not decide if my birds are SF - DF - SF (split into blue) or DF (split into blue) . Can you please tell me their full name? I need your help

Number 1:



Number 2:


Number 3:

Thank you for your answer Rancel but i need certain information because my aim is to get Silver & Blue goldians.

Number 1 - single factor

Number 2 - double factor

Number 3 - single factor

I'm not very good at this but here is my guess:

#1 looks like RH-WB-DF YB, but might be SF YB. Hard to tell, usually I determine SF vs DF by the presence of a blue collar around the RH. If it is blue then SF YB if no blue then DF YB.
#2 hard to tell from the pix, but "I think" also RH-WB-DF YB. I can't see the collar around the red.
#3 RH-PB but I cannot tell if it is a dilute or GB, I need a better shot of the back. It might be a dilute.

As for splits, I do not think there is any way to visually determine if a bird is split for another color. The only way I know of is to breed them with a known bird, then see what colors come out, or do not come out. This is how I determined that one of my hens is 95% NOT split for blue. 7 chicks from her mating with a blue male, and none were blue. I discovered that my both my RH pair M and F were split to OH because I had OH chicks from them.

This is one reason that I do not like working with splits. Unless I KNOW and TRUST the breeder, I have no way to verify the split, until I breed the bird. This is very important if I am relying on the split color. Second, it takes more time to get to the target bird color. Third is knowing the chicks, example, rather than mate a GB/BB to GB/BB to get a BB, I mated a BB to a GB/BB. That way I KNOW all the GB are really GB/BB. This makes planning to mate the offsprings easier.

Go to this site, you can input the colors to help plan your breeding

#1 SF
#2 DF
#3 SF

There is no visual way to tell a split to blue gouldian

I agree with Dayna and Debbie -

1: SF
2: DF
3: SF

#1 SF
#2 DF
#3 SF

There is no visual way to tell a split to blue gouldian

I agree

First of all , thank you for your interest. So you say the father and the mother should be known. Well, number 1 and number 3 are from the same mother & father but from different hatch.

I can also add a photo of their father & mother. Here they are :


Furthermore, i can tell you what colour babies i had from this pair in 3 hatch:
1-) Read Head - Purple Chest - Green Back (2 male)
2-) Read Head - White Chest - Yellow Back (1 male)
3-) Read Head - White Chest - Yellow Back (1 female)
4-) Orange Hd. - Lilac Chest - Yellow Back (7 female)

#1 looks like RH-WB-DF YB, but might be SF YB. Hard to tell, usually I determine SF vs DF by the presence of a blue collar around the RH. If it is blue then SF YB if no blue then DF YB.

A very easy way to tell SF is by the grey chin. This particular bird is visually yellow body because of the white breast. If it had a purple breast it would have a green body.

#2 hard to tell from the pix, but "I think" also RH-WB-DF YB. I can't see the collar around the red.

Being a yellow the chin will be white on a DF, it's not easy to tell white from grey but I think it's white so a DF.

#3 RH-PB but I cannot tell if it is a dilute or GB, I need a better shot of the back. It might be a dilute.

This one was the easiest to tell, by the grey chin it is a SF or what you call a "dilute"

Your male looks to be a RH.WB.Yb and the hen RH.PB/WB.Gb
Because you are getting WB chicks you know that the hen is split to WB.
If you are getting Yellow Head chicks then both have to be split to YH. If you look at the tip of their beaks, if it's a red tip they are RH, yellow tip then they are YH.
The breast color of a PB hen is a lighter purple shade then the males. The hen in the picture is a PB. A LB hen's breast is a very light almost pink color though there can be variations in the shade.
Nothing in their genetics would lead me to believe they are both split to Blue but you never know sometimes hidden genes just pop out and surprise you.

From this pair:
you will only get SF males, WB or PB/WB. The WB will be visually yellow body and the PB/WB visually Green body

all your hens will be Yellow body either WB or PB/WB

Beautiful birds, best of luck with them.

Thank you for your answers. I think i understand better how body colour inheritance works. Thanks again for valuable information

Play with the forecasting site.
That is one way that I learned about color inheritance.
Put a color combination in for M and F and see what kind of offspring they might have. Then start adding the splits. At a certain point with many splits there could be a HUGE number of combinations.

Debbie
Thanks for the tip about the gray chin.
I had been using the presence of a light blue collar around the red head to tell me SF or DF.
