Definitely keep taking piccies - I would love to see her from different angles too, and as she grows it will be really fascinating to see her facial features. Also do you know who the parents are? Photos of the parents could be really interesting so as she grows we can speculate on whether she's looking more like her Mum or her Dad.
As for media, definitely go ahead with the Practical Poultry article first. Then once it's published you can show it to more general media and see if they want to do an item. It means Practical Poultry will have done the leg-work and explained all the concepts in simple language that non-specialist journalists will be a ble to follow.
That's often the route a news story takes - it gets published in a specialist journal then later (sometimes ages later) it gets into the general media. Then everyone who already knows about it rolls their eyes and says "that's old news!"
