4 chickens injured

[GlowBean]

Hello! We have a total of 13 chickens (2 deaths Gunpowder and Beelzebub/Bubble) Though sadly, Shotgun, Soldier, Dusty, and Lemon. I call this "The Health check up" for my chickens. Let's get started!
Shotgun: Injured feet, walking around like he's dancing. - Me and my friend banadaged him up and is able to walk on them much better, doesn't wanna eat. 5 - 6 months old
Soldier: Just being bullied and lost a lot of feathers - She's recovering nicely, eating well and fantastically. Will be getting a sweater to keep her warm and grow feathers back. Turning 3 years old - My special baby~
Dusty: Blisters on her feet and one infect area on bottom foot - Me and my friend bandaged her up and she's still limping though able to walk. Not sure about eating. 5 - 6 months old
Lemon: Limping badly on her right foot and lost a lot of weight (10 - 12 pounds to now 7.5 pounds) - Splinted her leg with my friend, every now and then she eats. 3 years old

Going from from 10-12 lbs down to 7.5 is very serious. If your parents aren't involved in helping you take care of your chickens you're going to have to post their symptoms here and let us try to help.Your hen could possibly have sour crop, a compacted crop or have an obstruction farther down or have an unknown disease to cause her stop eating.Being lowest in the pecking order could cause the other chickens to bully her and not let her eat.

(I don't know what happened with the quoting something happened)
Lemon (Who went down to 7.5 pounds) is starting to eat again I made a separate food & water area that way she eat & drink nicely, she's starting to lay down every now and then though sadly she can't jump (very high) which is very worrying and I also expected that. Soldier is getting her sweater soon she has no infections no nothing other than small amount of bumblefoot (She's had that for (estimated) 2 years of her life and we just noticed this year). Shotgun he's bleeding every now and then though he isn't pecking at it which makes me a little worried if the others are pecking at the bandages on his feet. Dusty, I'm positive she has an infection. I will be taking pictures and make a video on how they're doing.
