Done it for the second time tonight too. First time was a very sick weak hen. Husband did that. This time it was 6 2mo cockerels. I had tried the rehoming route first for 6 weeks but no takers and I couldn't keep them any longer.
Was fortunate husband was home too. I held the bird and he used sharp bush cutters to cut the necks. I held the chicken until I could feel it no longer trying to flap... 20 to 30 seconds ish. We were doing it over the waste bin so once they stopped trying to move in my hands in plopped them in the bag in the bin. Went and got the next one and repeated this until we were done.
It felt remarkably less dramatic than I thought it would.
What helped
- read up a lot on here about it and made sure I was comfortable with the method we chose.
- prepared the bin and tools before etc
- made a list of things to do that day and added it on the list. So it was one of a few tasks to complete not the most daunting thing of the day
- knew it had to happen and wanted to be able to do all parts of chicken keeping myself
- was grateful my husband was on hand too.
Off to let my remaining pullets out. I guess they're a bit confused with the lack of brothers and crowing in their coop this morning

but they'll be in with the bigs asap
