Hatching eggs sellers...question

[SundownWaterfowl]

Ive waited 3 weeks, and all chicks hatched were purebred.

Then I should be good! I'll give it another week or so though before I offer any up for sale, just in case. Yes, keeping them penned seperate sure would solve that problem, LOL, but I had them all together for the winter for extra heat, and to reduce watering chores lol. My blue laced reds have been seperated now for almost 4 weeks, will be four on monday. My buff orps have only been seperate for 2 weeks, cos of a pesky maran rooster that somehow kept finding a way in until I moved him out of the pen altogether. My marans and EEs have a while to go yet though.

Man now that I know my eggs are good already I wish I hadnt ordered those last six eggs to fill the bator. Aw well, I guess once this first hatch is done I will do a hatch of all my own eggs. They should be all good to go by then.

This chicken breeding is addictive! I can't wait to see what my own blue laced red wyandottes look like! I have a beautiful blue rooster with a perfect rose comb over a blue and a splash hen. All have wonderful lacing! I'm excited!

Thanks everyone.

Oh blast .....I have to look for the book

Hagedoorn If I spelt it right....also wrote on this subject & observed observed chicks were sired by the new sire from eggs collected the day after putting him in the pen. That's from memory; looking for one book is enough for right now

. There's also a paper, somewhere discussing males releasing more sperm upon mating with new females & the mating frequence is greater.....I think I've got that right but as I can't remember where I found that so I cannot check it.

Right...... about the name...From Poultry Breeding & Genetics (for ease PBG).... "The sperm storage tubules located in the infundibulum have generally been referred to as sperm nests & those in the uterovaginal (uv) region have variably been referred to as uv sperm host glands, uv sperm storage glands & uv sperm storage tubules."

There are quite a few pages in PBG devoted to the findings of research on this subject. It is interesting to read but far more than I can type. I'll just type a few bits which seem relevant to the topic.

Right....again from PBG "Compton et al. (1978) found that when genetically labelled spermatazoa inseminated sequentiallyinto the domestic fowl, the spermatozoa became stratified by genotype within a sperm host gland over time, & emptying of a gland occurred as a sustained leakage of the most superficial sperm cells. These were significant observations, for they demonstrated that the spermatazoa from the last insemination were the first sperm cells to be released for purposes of fertilisation. Stratification of spermatazoa within the sperm host gland explains earlier observations whereby the majority of of progeny were derived from the most recent mating or insemination. It was erroneously concluded in the earlier studies that the result was the result of a competitive advantage for the fresher spermatazoa.

Compton et al. (1978) also found that the storage capacity of the sperm-host glands can exceed the functional life span of the stored spermatazoa. These observations taken together have very important genetic & evolutionary implications, for they demonstrate that the great majority of the progeny will be derived from the most recent mating, which may, in many instances not be the most dominant or desirable sire.

Van Krey et al. (1981) proposed that sperm cell agglutination may be the basic mechanism controlling the storage & release of spermatazoa from the uv sperm host glands. The ability of sperm cells to agglutinate is dependent upon intact plasma membranes. Accordingly, as spermatazoa age & lose cellular integrity, they also lose the ability to agglutinate & are selectively eliminated from a gland.............."

There are pages & pages on this & related subject such as seasonal decline in fertility..... which is quite interesting.

I'm pretty sure, without rummaging through PBG again that sperm life is variable. If my memory serves decreased sperm life is one of the pleiotropic effects of the rose comb gene when homozygous....I don't really remember but it may also have a lesser adverse effect when heterozygous.

Best wishes
