SL 44 Large Chicken Glasses

Product Overview

The SL 44 large chicken glasses carry printed dimensions of about 7.8 cm across, 3 cm high and 2.6 g per pair. The wide span is what sets this model apart: it is built for roosters, heavy dual-purpose hens and exhibition birds whose beaks are too broad for the medium frame. In the photo, a white fixing pin sits ready in the frame, and the red shells show the faint inner molding marks typical of this production size. The wide bridge spreads the grip over a large beak, so the frame does not dig in even on a big male bird.

The spectacles sit in front of the eyes and narrow the forward field of view, so a bird still recognizes feed, water and nearby chickens but spends less time staring at the feathers and tails beside it. On roosters, this calms repeated picking at hens during the breeding season. The red shells also cut glare on sunny ranges, which matters for heavy breeds that spend long hours outside. This listing covers the SL 44 large glasses together with the white fixing pin.

Key Features and Benefits

• Wide 7.8 cm bridge - The broad frame fits roosters and heavy breeds, where a medium size presses too tight or slips off.
• Printed size reference - The 7.8 cm width and 3 cm height let buyers confirm the fit against their birds before ordering.
• Light 2.6 g shell - Despite the wide span, the pair weighs only 2.6 g, so a large bird carries it without discomfort.
• Fixing pin included - The white pin threads through the nostrils and locks the frame, which holds up in active breeding pens.
• Calm breeding behavior - The narrowed view reduces a rooster's repeated picking at hens, protecting plumage through mating season.
• Glare-cutting red shells - The red plastic softens strong sunlight on open ranges, where bright light can stir aggressive pecking.

Materials and Quality

Each pair is molded from smooth red plastic with rounded wing edges, so no rough corner presses on the bird's face. The wide bridge is thicker than the medium model, which keeps the frame centered on a large beak rather than twisting sideways. The white pin is checked for a snug fit through the frame loops, because a loose pin is the most common reason glasses fall off. Before packing, we flex sample frames to confirm they open for fitting without cracking, and we reject any pair with flash along the shell edge. The wide shells are also checked for even wall thickness, so the two sides of the frame match in weight and do not pull the bird's beak to one side.

How to Use and Maintain

Hold the bird securely between the knees or against the body, open the wide frame over the beak, and push the white pin through the nostrils to lock the spectacles in place. Work in a calm, lit pen so the bird stays still. After fitting, watch the bird for an hour to confirm it eats, drinks and preens normally. At culling time, before transport or before a show, take the frames off, wash them with warm soapy water, rinse and dry them for the next batch. Discard any frame that cracks, and replace a bent pin rather than reusing it.

Applications

The SL 44 is first of all a rooster and heavy-breed product. Breeders use it on male birds shared with laying hens, where constant picking damages plumage before mating. Exhibition owners order it for heritage and show breeds, because intact feathers are part of the judging standard. Free-range farms on open pasture also choose the wide size, since heavy hens on bright ranges often outgrow the medium frame within one season.

Distributors stock the wide size alongside the medium range, because customers who raise roosters or dual-purpose breeds keep asking for the broader frame. At 2.6 g per pair, the glasses pack densely into bags, which keeps the landed price low. Poultry extension teams recommend this model to new growers who have tried the medium frame and found it tight on their larger birds.

Frequently Asked Questions

Q1: How do I know whether my rooster needs the large size?

If the medium frame sits tight on the beak, slips off after a day, or leaves a mark on the nostrils, the large size is the right upgrade. The 7.8 cm span covers most common rooster breeds.

Q2: Can the glasses stay on during mating?

The frames are designed to remain on while the birds feed, walk and breed. Check the male bird after a few days, and refit any pair that has shifted.

Q3: Is the fixing pin included?

Yes, the listing shows the wide frame together with the white pin. Spare pins are available if you lose any during fitting.

Q4: Can I reuse the glasses next season?

Yes. Wash the frames in warm soapy water, rinse and dry them between batches. Replace cracked frames or bent pins before the next use.
