LITTLE Harry Lea couldn’t believe his eyes when he went to collect the eggs from his school chicken run.

The youngster ran back into school to show his classmates his eggstraordinary discovery – weighing-in at an eye-watering 119.5 grammes or 4oz.

The find at Shelley First School eclipses the size of the 100g (3.5oz) egg found by six-year-old Rhienna Kitt in her Lower Cumberworth garden earlier this week.

Teacher Linda Green said: “We’d never seen anything like it – it was absolutely egg-normous!

“There must be something in the water around here. I would like to say it’s our Shelley charm.”

The school introduced the idea of keeping hens last September as part of its bid to become more eco-friendly and self-sustainable.

The eggs are sold as well as cooked by kitchen staff for school lunches.

Each class is responsible for a hen and the children take it in turns to look after them.

The hens, which came from a breeder in Penistone, are named Beetroot, Doris, Snowy, Speckly and Ginger Nut.

They usually produce one egg each a day and the eggs collected are normally quite large.

But the staff and children had never seen anything like the latest one.

Linda said: “One of the children was on chicken duty and went to collect the eggs and he came running back in with it saying ‘look what I’ve found!’.

“It’s now been passed around the whole school. We’d never seen eggs that size before and were absolutely gobsmacked.

“We checked the size and it was almost 120 grams – double what hens usually lay.”

The hens have a pen but as they are free range they are left to wander freely around the school grounds.

They enjoy extra nibbles from leftover lunchtime scraps like pasta and Linda believes this could have something to do with the size of the hen’s latest product.

“We have no idea which hen laid the egg. We think it could be either Beetroot or Speckly because the red combs on top of their heads are bigger and it’s a sign that they’re laying eggs.

“I think we’re going to keep it, perhaps have it blown and decorated – although it would make a very nice omelette!

“It’s a lovely Easter present for the school and we’ll be on the lookout to see if we get any more.”

A spokesman for the British Egg Industry Council said that an egg over 73g is deemed to be very large.
