In the egg. When chicks hatch they have little nubs that can grow out latter resulting in a spur. Hens can grow spurs too. Sometimes only one spur grows and leaves the other as a nub. The spur can get knock off and never grow back.
Bantam rooster spurs are probably the longest. The average measurement is about 3 inches
Some Cochins don't grow spurs. I had 3 Cochin roosters that did not grow spurs.
No. The rooster is the male, the hen is the female. Some rooster breeds do not grow spurs at all.
A rooster spur is the bony like horn that grows on his legs which he uses for fights with other roosters. Some hens may also grow smaller spurs.
The rooster will grow a spur about 2 inches above the back claw and inside the leg. Hens do not grow spurs.
spurs are hard knobs on the rooster's legs, near the feet. They are often pointed and can be quite long.
It really would depend on the size of the rooster. Spurs will grow to a certain length and then start to curl. They will curl more than once but it is hard on the bird. Walking becomes difficult. Trimming spurs is not that hard.
Most hens have small, or almost nonexistent spurs. Only occasionally will a hen grow long spurs. There are some breeds that may be more likely to grow long spurs, such as Lakenvelders. Male Lakenvelders grow very long spurs quickly, so the chances of a hen growing long spurs as well may be increased.
They can grow spurs, but normally they don't. Often, a very dominant hen will grow spurs, or a hen that has a need for the extra protection, such as a hen sitting on eggs. I have a very small hen that is low on the pecking order, but very feisty, and she only has one long spur on one of her legs. Also, if there is no rooster around, sometimes the dominant hen will take his place, often growing longer spurs. All chickens have at least very small spurs, and the potential to grow long ones. Typically though, hens won't grow long spurs.
No there not poisonous
A rooster
They grow as the rooster grows. We have some juveniles that are a few months old and theirs are about 1/2 an inch long. Our mature rooster that's about 3 years old (his father was murdered a few months ago and he became the alpha male) has spurs that are 2 1/2 to 3 inches long. His father's were probably about an inch longer than that when he was murdered.
Trimming or cutting the rooster's spurs are done for several reasons. The most important reason is that then hens are being injured when he mounts. It does not hurt the rooster -- it's like removing tough skin from your outer toe. The tough part doesn't feel anything. There's only the pressure of moving it around on the softer skin.You can trim two ways:Cut the spur off with plant trimmers or a small saw.Twist the spur and it will pop off leaving a smaller core spur.How often this needs to be done depends on how fast your rooster's spurs grow, and how long you keep the rooster in your flock.
