I think Benny makes a good point. What prevents unwanted bacteria from entering the edges of the hole, 'specially given the chickens' habit of walking in all manner of bacteria-laden,potentially harmful stuff? What prevents the hole from closing just like pierced ears will without earrings in them? If the feet are muddy, how can you even see a small hole in the foot?
I agree, with the hole leaves open edges and a chance for bacteria. I have tried other methods of marking chicks. None are perfect.
However, there are a lot of things I have to do I do not like. I am required to check my flock of for MS and MG every 90 days. this requires poking the birds and taking blood. I am required to test for AI every 3 months which means trachea swaps. They require I do several birds on one swab, which to me is spreading a disease and bacteria. The USDA Vet and State Vet say it does not matter and the chances are low.
This is my first time with toe punching. I am not sure how I will like it. I need to keep strains separate and in some cases know the parents and lineage of the chicks.
I put the chicks on 1/4 in hardware cloth, something many do not like. I am not the biggest fan of it, but it does keep the area drier than paper lining and bedding.
I am constantly trying to refine my hobby and find better ways to do things. I worry about the bacteria, I suppose I could try a little peroxide in each hole but that runs its own risk. I have also read they may need to be repunched in a couple weeks, Something I do not look forward too.
If I lose a bunch from this batch because of infection, I will try another method, what I am not sure, but I will look for other answers.
I had thought small "parrot" leg bands would have worked. I tried them last year. Do you know how many of them are Houdini wannabes and can escape leg bands?
I sold 3 Buckeyes I had by mistake because they escaped the legbands. (my only 3). They went as SS's which means someone was disappointed in their SS and I was in losing my Buckeyes......Chicks change so much in the first few weeks and can be mistaken so easily.
I assume my wife or kids or the neighbor that works for me some sold the buckeyes. I surely could not make a mistake myself. My last mistake was in 1993.
Did you try those?
