I've been doing some test hatching (of my whole flock- not just marans) now that I own 3 incubators LMFAO. (I know not unusual but my family thinks I'm nuts).
I just candled my eggs- taking notes on who's eggs are always clear, who's are getting blood rings, who's look good, porous etc...
And I have some questions.
1. If I collect 9 eggs from one hen, and 4 are clear but the other 5 are looking great- how is that explained? I have one hen who lays (almost)everyday, so I have eggs labelled 5,6,7,8,9,10, 11, 13, 14,- how can she have infertile eggs in the middle?? (her eggs are almost white- a tint colour, so easily candled.) Also, she is my only hen with this colour egg in that pen.
2. my Silver laced Wyandotte's just finished their moult mid jan. Their eggs are suddenly pointy and very porous- doesn't look like they are developing, although I know they have been mated because I have seen it several times.
What can explain the pointyness and porousness? Is this why they are not developing? No, they weren't pointy or porus before they moulted.
3. if a particular hen often develops a blood ring in her eggs- is this just coincidence or could this be a trait of hers?
4. I have 3 lavender Orpingtons in a pen with their rooster. It seems like two of them are not being mated. I watch him chase them around, but they do not let him. He is lovely and polite with them, does his dance etc... a nice rooster. How shall I encourage their compliance?
Sorry this post is not Marans specific, but I trust the opinions of this group.
chooks that are not selectively line bred for those traits will not be predictable when bred . they will express all sort of mixed traits .
for a pair of chooks to have all they eggs fertile many many years of selective breeding has to be done .
select the compatible pair and work with .
if a hen does not like the rooster than you should not keep them together . nothing will happen .
if the eggs have a funny shape or deformed ,do not incubate them . add vitamin B12 complex to the breeders water to solve this issue .
