Hi Ray,
Just for your info, this may be if interest.
My Sister-in-law looks after her kids school's chickens. They have about 12 Silkies (with a couple of others that they have 'taken in' ) chosen for their temperament. It is a small rural village school backing onto fields & countryside. They have made a 6/7ft high wire netting enclosure in a suitable corner of the grounds & are lucky having a lot of willing parents to help with these things! Also being a small rural community they have knowledgeable locals on hand who can give advice (& deal when necessary) with a variety of issues as they arise (foxes, rats, etc)
They raised the money to buy the chicken coup in various ways as schools do!
As she lives literally opposite the school door, so school holidays aren't a problem.
Another lady I know gives her village school 20 fertilised eggs each summer term & the project is to hatch them & raise them till the end of term then she has them back.
Best of luck,You'll be hooked yourself never mind the kids :lol:
