Pecking Injuries on Combs

[My Three Chicks]

Hi. I'm in the process of integrating 2 new chicks (15 weeks old) with 2 existing chicks (18 weeks old). All-in-all its going well. We did the 'look, but no touch' for the first week and now they've been all together for 1.5 weeks. Just some chasing and a little pecking.
My 2 newbies have some wounds on their combs, wattles, face. I've been cleaning and spraying Vetericyn as needed. I have Pick-No-More but haven't applied any. Can you look at the pics (2 pics of my Dominique's comb injuries and 1 of my Red Sex Link wattle, side of face, and bump on comb) and let me know if I should be concerned or do anything else? Poor babies.

Generally I don't put anything on minor peck wounds.
The Vetericyn is ok if that's what you've been doing. I would not use pick no more, to me it just attracts attention.

The drama usually settles down after a few weeks if there's enough space for all.
