Gold Comet Pullet Comb/Waddle Color. Worm concern?

[StuBri]

So I have six gold comets that I got as chicks, and they are now almost 16 weeks old. Four of them still have quite small/pale combs and waddles. Two of them have larger red combs and waddles. Roughly when should I expect them to turn fully red and start laying? I thought this was to be expected around 16 weeks. They don’t seem to be lethargic. It has been hit here so they’ve been hanging out in the shade a lot, but so would I with the heat we have had lately!

I noticed today that one of them had diarrhea, but I think it may be because my wife left too many treats out for them last evening (veggie scraps). Should I be concerned about worms or anything else?

My gut is that everything is fine with your flock. 16 weeks old is a bit on the young side even for sex links. Different birds mature at different times. The four with smaller 'wattles' are just maturing more slowly than the other two.

Thanks! Cleaned out their coop and they seem to be acting fine.

Yeah, cool it on the 'treats'.
The loose poops may be from the heat,
they drink more and it goes right thru them trying to shed heat from the body.

EL and ice blocks helps here with the heat:
