Last year, I hatched silkie chickens with my class. Two hatched and survived, a rooster and a hen. I took them home for the summer and for various reasons they haven't come back to school.
They're moving in on their newly-wheeled hutch this weekend.
Whatever else the New Year brings my classroom...well, this should be a lifelong memory for all involved at the least.
With any luck it will keep the class from asking where the isopods went (for environmental and cruelty reasons, releasing them is not an option, so using FOSS kit recommendations they were euthanized via freezer).
