I asked about eye color not down a while ago, last year, but haven't seen any results yet. Now that I have my own birds who knows what will come about. Junk maybe.
Snowbird, how are you using those barrels in your album? Do your birds ever range?
Another question:
Let me lead with this; I keep Orloffs here, not many, but I do. I was on feeding level with my orloffs and comparing head shapes. I have one female who has a nice wide brow and the others are more narrow-- a result of breeding. The wide is where its at but most folks don't know to even look for it. This comes to Marans because I was looking at pictures of Mr Don's birds and referencing them with some BCM that a woman has had for some time here in Maine. Hers are all melenized or very dark. Hers, and I would say Don's, appear to have thick, very round heads/brows. Two of the ones I have do have good color but their heads are more... well these girls remind me of fine porcelain tea pots. The head is narrow on the neck. I don't know how to describe this any better. Its about how big the head is on the neck. I wondered if this was a trait that indicated lineage or if it was a trait that should be watched in breeding... or if it doesn't matter at all.
Head structure is something I breed for in all my breeds and feel it is very important as it can change the overall look of a bird very quickly. Here's an example of the head shape I am breeding for and am getting more consistently in the Marans. You are right that there is a large range within the Marans when it comes to head shape.
