The Swift you took a picture of is not a good flyer...unfortunately they are not cheap...the flying ones are in the bolk mesawed and you will not really find them any more..very hard to find and expensive..
I have some ES for sale check out the Doneks and Divers runboard site for the pictures and I can take more picture if you want.
My first pair of Ottati's came out of the imports. That's one pair from its parents. Through the years those birds I raised either stopped laying or would lay only one egg if even fertile. Those that were fertile eggs, the chick would die the day before hatching or the day of hatching. This is all caused by too much inbreeding. A well known ES breeder told me that if you can raised two to three baby's each year out of a pair of Gohzar's (Egyptian Swifts) that is doing great. The good birds are expensive to buy in Egypt and the importation fees are nuts. Yes these are expense rare birds.
With all this said: In 2011 I crossed two American Show NPA Standard Egyptian Swifts: Spread Black, Sooty. Dirty, smoky, T-Pattern Check, Indigo (Andalusian) to a pair of my pure stock. I kept six of the better (1/2 Ottati) hens. The rest went for dog training.
2012: Out of this six pairs I raised 26 babies. I will keep six (3/4 Ottati) hens and two (3/4 Ottati) cоcks to mate to my pure breeds.
That leaves me with six 2011 hens to dispose of and 18 (3/4) Ottati-(1/4) American Standard Egyptian Swifts to sell. These 18 do fly with my Homers. So the Gohzar flying ability is in these birds. The American big fluffy show type birds lack the flying ability due to size.
Also the 3/4 birds beaks are too long and the heads aren't the right shape yet! Some almost have the right eye color. The eye colors are different in the 12 different Gohzar breeds. Ottati's have Brown Gravel or Pearle Gravel eyes.
The above is my disclosure of the mixed heritage of the 24 birds for sale.
The six 2011 hens I am asking $4.00 each. The 18 (3/4) Ottati's I am asking $10.00 each.
