Same here, easy if one is withered or much smaller otherwise I feel like a horticultural axe-man.
What I did with my extra sprouting broccoli seedlings was to keep them in pots and stand them alongside the ones growing in the ground under the cloches, even-so, I planted the broccoli too close together because I had the plants. I suggest to myself that I can always thin them later but I never do.
My kale was planted too close together though I think the only problem was some lower leaves start to go yellow, no problem, I prefer the top leaves though because they are rubbing on the enviromesh the top leaves have a sort of beige discolouration. Even though they are large plants planted too close together the weeds manage to grow between them.
