When I put that cockerel in the layers pen, and let them out into a large, fenced area, I had noticed several weeks ago that he did not like a certain pullet. Not one bit. What did he know?
I keep flocks by pens and let them out to scratch and range about, by group. The day was gorgeous in early October. In the sunlight, one pullet from that pen really stuck out. Her feathering looked as if she had been fed nothing but 28% Gamebird feed for two months. In reality, they'd all been fed the same 17% layer mash since September.
I also noticed her gorgeous yellow legs. The rest of the dozen were losing their yellow tint in their legs quickly. Top layers give up their yellow within two months of heavy laying. As given in the original briefing for the Pop Quiz, all these birds are 8 months old. The began laying in early September. Folks, it is now early December. Remember, the briefing also stated that these are NOT dual purpose breeds. They've no body to them at all. There isn't enough to make a decent cup of chicken noodle soup. LOL
An ISA's particular "beauty" of "form" isn't all that important. Remember, these are not a breed, therefor there is no SOP for them to meet at all. It's almost irrelevant, as these are layers and that's it. Here's my original Pop Quiz background:
There are two birds focused on here. I will try to identify them simply as Bird #1 and Bird #2. They are both ISA Browns, the quintessential layer. Think the CX of the layer birds. These are not dual purpose fowl. They are dedicated purpose fowl. Eggs, eggs and more eggs. They are both 8 months old, all the birds came in a box of 25, hatched on the same day, brooded together and raised together. Always been fed the same feed, in the same environment.
