My roosters have a specific alarm call for aerial predator that sounds like a cross between a growl and a gargle. "Aerial predator" usually turns out to be the resident Cooper's hawk, but it could also be a fast-flying dove, or an airplane overhead. Anything unusual in the air that looks threatening. Glad you found your pullet. Sounds like she's a keeperOh I found my pullet!!!!something definately scared them all and apparently she went up into the orange tree while everyone else ran to the coop. I looked all over and couldn't find her but once I took out the mealworms she came out. Yippee! Still wonder what spooked them
I did order one red sexlink from ideal and it looks identical to the "breed standard". This one has black in her tail and wings and looks different than my rsl but if there is no true standard to the breed they may have sent me two rsls. Is "production red" a different bird than a rsl?
There is no "breed standard" for a red sexlink. It's not an actual breed. It's a cross between birds with different, sex-linked color patterns that produce chicks whose sex can be identified by down color. Hatcheries love to produce these sex-link chicks because there is so much demand for female birds and these sex-linked color crosses allow the hatcheries to readily identify which chicks are female and which are male.
A "production red" is a label indicating a generally red-colored bird developed for its egg-laying ability and not conforming to any particular breed standard. The high emphasis on egg production sometimes compromises other qualities like longevity. A lot of people mistake "production reds" for Rhode Island Reds. A true Rhode Island Red is an awesome-looking bird of a completely different shape than any "production" chicken from a hatchery.
