Yesterday we had friends come over who have unruly children, it was a surprise drop around so I couldn't do what I normally do which is lock the cage and place it in my bedroom (out of sight out of mind) I was in the middle of cleaning my outside pen, so I placed the lock on left them there (didn't want to insult friends by making it obvious I don't trust their children) said to my Husband watch the chicks please. So I am in the pen and I get the this sick pit of my stomach feeling and thought I need to check the chicks so i immediately went inside to check. My Husband had gone out the front leaving those children with the chicks and the elder one had unlocked the cage grabbed my favourite silkie and had it on the floor and was pushing down with his hand on top squishing the chick. I have never yelled at another persons children like that, those kids were lucky all I did was yell at them. I grabbed my baby straight away and she was very limp but still alive, she has perked up on and off since but majority of time she has played in the one spot, I have had to pick her up and take her to the water and dip her beak in it or she ignores it. I have checked all her bones which seem to feel normal and in the right places. Im thinking either she is very bruised or worse there is some internal bleeding but her poop is not runny and there is no blood. I don't want to leave her in pain as much as I love her and want her to pull through, if it is more humane to cull her its what I will do. What do you guys think just severe bruising or more serious?
