I'm extremely new to being a chicken owner so I'm lost on a lot of stuff, google is mostly helpful but not so much with this question. I have 6 Barred Rock chicks I bought about a week and a half ago, they don't have head feathers and they are seeming to get their breast feathers now which from a guide I read places them about 4 -5 weeks old. But when I look at pictures of same age barred rock chicks, mine look fairly older. Could anyone help with the age of my chickens? I want to get them outside soon because they are quickly running out of room in the garage. Also, only one of the has started to develop a comb, I have also noticed that the one who is developing a comb is more aggressive than the others and their tail feathers are MUCH shorter than the other chicks. I'm afraid it's a rooster as I can't have roosters where I live due to ordinance. So is it likely it's a rooster? Or do some chickens get their combs early on? Also the comb is pale which I read is a sign of health issues, but I wasn't sure if that only meant older chickens so should the comb be red or is pale okay since it's just now developing. Apologies for the long post and all the questions but any help would be extremely appreciated! Thanks so much!
The chick with the comb and shorter tail feathers.
The entire flock, I think they are 4-5 weeks.
