Not necessarily - a neighbour has a cat who used to "work" as a stud cat but wasn't a happy employee. The females bullied him shamelessly, and wouldn't let him near the food bowls, so he is enjoying his retirement as the only pet in the house. He had never been out into a garden, and would be completely unstreetwise if he went out on his own, but he likes to help with the gardening. and stalk birds (unsuccessfully)
And the original report from the researchers is at bmcbiotechnol.biomedcentral.com/articles/10.1186/s12896-018-0495-1 This should be genuine and a a serious report of serious research - ^"BMC Biotechnology is an open access, peer-reviewed journal that considers articles on the manipulation of biological macromolecules or organisms for use in experimental procedures, cellular and tissue engineering or in the pharmaceutical, agricultural biotechnology and allied industries. BMC Biotechnology is part of the BMC series which publishes subject-specific journals focused on the needs of individual research communities across all areas of biology and medicine. We offer an efficient, fair and friendly peer review service, and are committed to publishing all sound science, provided that there is some advance in knowledge presented by the work.""
I noticed that too! Perhaps it wasn't explained to him clearly enough that the cockerels were there purely for their contribution to chick production, and he himself added the other bit. Many people believe that hens only lay eggs after fertilization (like humans only have babies after fertilization) but the truth is that they lay without ever meeting a cockerel.
Journalists are not famous for their accuracy on scientific matters. I don't think I would disbelieve the rest of the story, though. The Roslin Institute is a respected establishment and wouldn't be a party to invented news.
“There are cockerels here too, something of a surprise to a townie like me. Their purpose is twofold. Hens won't lay unless there's a cockerel in the vicinity.” ???
Oh yes they will! That is so blatently untrue I cannot take the rest of it seriously
It sounds as though these chickens are living the life of Reilly, and regulations will make sure future generations of lab-pharmed hens are also well looked after.
