SL 45 Medium Chicken Glasses

Product Overview

The SL 45 medium eye shell is marked on the product card at about 5.5 cm wide, 2.6 cm high and 1.2 g a pair. The product line ships in two versions: one with small eye holes, and one solid without them. The sample photo shows the red shell with a white fixing pin seated in the bridge. Because both versions share the same bridge and pin, a farm can order both and match the shell to the severity of pecking in each pen, rather than applying one treatment across the whole house.

The shell itself sits over each eye and blocks the direct forward view, while the pullet keeps enough side vision to move, feed and drink. Where the shell carries small perforations, some sunlight passes through, which pullets find less restrictive and calmer. The solid version blocks more view, so it is chosen when pecking has already become a habit. The red resin filters bright light without darkening the pen. The range includes the SL 45 medium shells with the fixing pin.

Key Features and Benefits

• Two shell versions - Pick perforated shells where pullets need light through, or solid shells where pecking is already severe.
• Printed 5.5 cm span - The marked width and 2.6 cm height confirm the medium fit on adult layers before ordering.
• Ultra-light 1.2 g pair - The thinnest shell in this range rests on the beak almost unnoticed by the pullet.
• Daylight through eye holes - The perforated version lets daylight filter in, which young layers accept faster than a fully solid shell.
• Pin-secured bridge - The white pin through the nostrils holds the chosen shell in place for the whole rearing round.
• Compact medium size - The span sits between the small chick model and the large rooster model, covering ordinary adult layers.

Materials and Quality

The perforated shells carry small holes shaped in the die, so the openings are clean rather than punched after production. The solid version has a flat inner surface, and both share the same bar shape and pin bore. We inspect the holes to make sure no rough edge blocks them, because a partly blocked opening defeats the purpose of the perforated version. Check shells are opened and shut before packing, and the pin threads in without forcing.

How to Use and Maintain

Choose the shell version first: perforated for open pens, solid for closed barns where pecking is bad. Hold the pullet still, open the shell over the beak, and secure the pin through the nostrils. After fitting, check that the bird moves normally. If a pen's pecking worsens after a week, swap that pen from perforated shells to solid shells rather than changing the whole house. At the end of a rearing round, remove the shells, wash them in mild detergent and water, and look through the perforations to confirm no dried dirt blocks the openings. Store the shells flat in their bag, so the bar does not bend out of shape before the next batch.

Applications

The perforated version suits open-range pens, where pullets still need to judge light and weather through the day. The solid version suits closed barns, where pecking has started and a stronger view block is needed. Breeding pens use the SL 45 to keep plumage intact before mating, and exhibition farms use it to protect show birds during the growing season. The perforated openings sit high on the shell, so sunlight reaches the retina while the direct line ahead stays covered.

Resellers stock both shell versions because customers ask for the choice, and the medium size is the fastest-moving option for ordinary layers. At 1.2 g a pair, the shells pack extremely densely, which keeps the landed price low. Farmers also like choosing per pen, because a calm open pen on perforated shells does not need the stronger view block of the solid version. New pullet rearers start with the holed option, since the milder effect is easier on young birds still learning the barn routine. Order both versions together, so a buyer can match the shell to each pen on delivery day rather than reordering later.

Frequently Asked Questions

Q1: Perforated or solid, which should I order?

Use perforated shells on open pens where pullets need light through, and solid shells in enclosed houses where pecking is already a habit. We can supply both in one order.

Q2: Are the eye holes formed in the mold?

Yes, the openings are molded rather than punched, which keeps the edges clean. During cleaning, check that the holes are not blocked by dried dirt.

Q3: Which birds fit the medium size?

The 5.5 cm span suits adult layers and medium breeds. For roosters or heavy breeds, ask for the large model, and for chicks ask for the small one.

Q4: Can the shells be reused?

Yes. Wash in warm soapy water, rinse and dry between batches, and check the perforations are clear before the next use.
