How to Use
How to take off the protective plastic cover:
- Hold in one hand so crayon itself is facing you.
- Push the crayon (hole in the center) with finger or thumb.
- Crayon should pop out.
How to install crayon into harness holder:
- Remove cotter pin out of back of crayon by making a slit down middle of sticker.
- Place narrow end of crayon (plastic side down) in wide part of holder.
- Gently slide up until it can go no further.
- Slide cotter pin through holes on side of holder and crayon.
- With needle nose pliers, bend end of cotter pin to lock in place.
- The shade of the marks on wool may not exactly match the crayon color.
- Store in a dry, cool place to prevent crayons from melting.
- Always check the ram every day to see if the crayon needs changing or the harness needs adjusting!

We have been using EZ-Mark® Crayons for several years on our own farms in southeast Iowa with good success. (Weather in Iowa can change quickly between very cold and very hot.) It has puzzled us that some have indicated the same good results while others have expressed disappointment.
Regardless, enough folks have expressed frustration—especially in hot or cold climates—that we felt an alternative must be offered. So we brought in marking crayons from a reputable UK manufacturer. COLD/SOFT and HOT/FIRM crayons are available from Nettex for folks who want to try a different brand.

Used these for the first time and the crayon was very clear on my Boers. I used green on all white rumped gals. Out of 25 does, 23 were marked and of those 23, we had 21 confirmed bred via ultrasound so I was very happy. I only used one crayon and checked each day for new marks or "darker" marks on previously marked does. Next month will tell how accurate my dates are.

These marking crayons work great. Our only problem is trying to decide which colors at what temp and how to layer them through the breeding season. We start with yellow and change to darker milder colors as the breeding season progresses. I think they are very reasonably priced as well.

Using marking crayons makes my life so much easier, I can't imagine not using them anymore, even for one ewe! :-)
I did have a question though- do you recommend buying "fresh" crayons each year? I noticed that some that I saved from last year didn't seem to work as well, I wondered if they tend to dry out in storage? Also, how "low" can the crayon get before it doesn't work anymore? Should they last all the way down to empty, or should they be replaced once the crayon material gets lower than the plastic sides?

This chalk fits in the harness better than other brands. I have found that the "hot" does not mark very well. We started using the "mild" even in hot weather. We also found that in a dry lot setting that hay and other stuff will stick to the chalk. We dont have this trouble in a pasture setting.

These are great! They work and it gives me a more accurate date on lambing.
