Breeding Alexandrine Mutations: Blue & Grey

In order to achieve a visual blue or grey, both parents must carry the blue gene as blue is a recessive mutation. Breeding a blue/grey is therefore more complicated than breeding a lutino. I don't have first hand experience of doing this but from my knowledge of genetics and extending what I have discussed in my article on the lutino, I would suggest the following.

STEP 1
Start with 2 pairs, all birds should be unrelated.

Pair One: Normal Alexandrine cock X Blue IRN hen
Pair Two: Normal Alexandrine cock X Grey IRN hen

Pair one will give you offsprings all of which are split to Blue. The good news is that you can use both males and females from here in step two.

Pair two will also give you offsprings all of which are split to blue. If your grey IRN was single factor grey then half of the offsprings will appear grey-green. If the Grey IRN was double factor grey all the offsprings will be grey green. You should use a grey-green from this pairing in Step 2.

STEP 2
You have 2 options here, both are equally good and your choice should depend on what offsprings look best and what is available.

option 1: Green/Blue cock from Pair one X Grey Green/Blue hen from Pair two
option 2: Grey Green/Blue cock from Pair two X Green/Blue hen from Pair one

This pairing should give you a visual blue and a visual Grey bird along with some grey-greens. The probability of getting a visual Grey or blue is 25% so you may have to try a few times before you get the desired result. You may also setup more than one pair in this step from birds of step 1 to expedite the program. The green and grey-greens produced here may or may not carry the blue gene. Since there is no way of differentiating between the two, it is best to not use the greens produced here.

Step 3 would look like step 1 except you will now use the 2nd generation Blue and the 2nd generation Grey instead of the IRNs. Step 4 would be similar to Step 2.

Breeding Alexandrine Mutations: The Lutino

Introduction The Alexandrine is a beautiful bird similar in appearance to the Indian Ringneck. The characteristics that distinguish an alexandrine from an Indian Ringneck include red-brown shoulder patches, a wider neck ring and larger size. While the Indian Ringneck is available in several color mutations the Alexandrine is generally available only in the normal green. It is possible to produce Alexandrine  colour  mutations by hybridizing the Alexandrine with the Indian Ringneck. Such a program however requires a long term commitment, space and responsible breeding practices to be successful and to preserve the purity of both species. In this article a breeding program is outlined that breeds a sex-linked mutation such as Lutino into the Alexandrines. To start the breeding program you need a good normal Alexandrine and a Lutino Ringneck. There are two options at the start of the program. 1) A Lutino Ringneck cock paired to a normal Alexandrine hen 2) Normal Alexandrine c

Getting Started with Breeding Ringnecks

Image
First of all you need to pick the right cage. Ringnecks require a minimum cage size of 24in x 24in x 48in. The front of the cage should be 24x24 with feeding stations. The depth should be 48inches with the nest box installed outside at the back of the cage. There should be a perch about 1.5-2in in diameter 6-8in from the back wall and just below the opening to the nest box. The logic behind such a setup is that the nest box should be farthest from human approach during feeding times. Birds feels secure in such an environment and are more likely to breed. The illustration below shows this setup. The mesh used for the cage should be rectangular weld mesh and not expanded metal mesh as shown in the picture. The nest box should be filled with white pine shavings 3in deep. The cage should be protected from direct wind and prolonged exposure to sun. While sunlight is great for birds, a shaded area in the cage should always be available to them. Once you have the setup in place, you

Alexandrine Mutations Project: Year 2 (2012)

Image
This post relates to my Alexandrine Mutations Project. If you are new to my blog you should start reading about this project here . To summarize, I paired up a normal Alexandrine cock to an albino ringneck hen last year to start my alexandrine mutations project. The hen laid 10 eggs in two clutches but all eggs were infertile. Here's what happened this year.   The pair was moved to a breeding cage in preparation for the 2012 season in September 2011. The birds were still bonded, perching together and the male feeding the hen. They however showed no interest in the nest box. As the breeding season peaked, the hen started to flirt with me again. She would jump to the cage floor and approach the feeding area where I would be refreshing their food and water dishes. She would then assume a mating position and make a cooing sound. I would ignore her and carry on with my tasks. The male would sit on the perch and watch the hen very closely. He was not very happy at the situation but
