I must have read it wrong.

Mine are still NOT laying I hatched them in July. Maybe they'll start in a couple weeks once I turn the light on them... Anybody got good pictures of their eggs? I now wish I would have taken a pictures of mine before I incubated them...

On spurred hens-

Spurred females are not common among heavy chicken breeds, but they are found quite frequently among Mediterranean breeds. Bauer(1931) was unable to find any abnormalities in the ovaries or endocrine glands of spurred females. His spurred females reproduced and grew as well as did his nonspurred females.

Others have also shown that spurred females perform well(Tandon and Iyer, 1954). However, Fairfull and Gowe(1986) found that spur length was negatively correlated phenotypically with egg production, egg weight, specific gravity and Haugh units, and positively correlated genotypically with part-record egg production.

Seasonal and dietary influences were not significant in influencing spur development in females, but the incidence of spur formation and spur length did increase with age(Christmas and Harms, 1982)

Goodale(1925) showed that spur development in females had a genetic basis and by selection he developed a strain in which half of the females developed spurs. He suggested that inheritance was recessive. Tandon and Iyer(1954) also showed that this trait was inherited, but their crosses gave mixed and not very helpful results.

Significant strain differences have been shown for this trait (Christmas and Harms 1982; Fairfull and Gove 1986). Experience of the author(Sommes, unpublished) and correspondence with an American Pit Game breeder whose females are spurred, indicate that when spurred females are crossed to light breeds(Leghorn, Polish and Sebright), most of the female offspring develop spurs. Further genetics investigation is warranted.

Thanks, gallorojo, very interesting.

Umh, what is part-record egg production?

 

[chicken potpie 2020]

i have one she is about a year old shes a sweet bird and will follow me around but the run at a drop of a leaf she free range all day every day and is really good at it i had to fight her for a while out of the blue she want to roost in a tree and not the coop every night for 2 week i had to go and find her with a flash light she just start to lay this winter and i get a white egg every other day just about i know its her bc everyone else is a ee or lays brown eggs

Yep! That's a big good looking egg! Have u noticed egg shell's and interier quality being any better than other egg laying breeds?
