Distressed Chick

Hi all,
A while ago I asked advice on what to do with a chick with splay legs, sadly 4 weeks later I have had to put her down. The leg brace seemed to work a treat, I left it on for 2 weeks and she was fine until 2 days ago when she started to go off her legs. I think there may have been a bigger problem going on

I hatched 2 chicks at the time, the other chick is hale and hearty and had been very protective of the other one. Now she is on her own she has been really distressed, she runs around the garden following me like I am her mum, hopping on my shoes when I stand still. If I hunker down she hops on my lap and snuggles in, and when I put her in the little pen and leave her she shouts loudly and paces up and down.

Yesterday was the first day, she is 4 wks old and too young to put in with the others. I have three 8wk old incubator hatchlings in a large pen, and 4 sets of hatchlings with mums ranging from 1wk to 6wks.

I would like to think I have done the correct thing, I gave her a pat and put her in a mesh pen in the middle of the garden where all the others free range and  left her to it. Figured the sooner she copes the better. At night I put her back in her little cage, the one she was in with the other chick.

Will she be ok on her own for now, in a couple of weeks she will be so much bigger and a couple of the other younger birds will be ready to leave there mums then I can put them all together.  Does this sound acceptable?

Any advice badly needed.

Thought about this, did try for a short time yesterday and they did not make actual contact but did have a bit of a gow, she was sooo scared. I'm being soft arn't I!!!

I am at work today and tomorrow, so I thought I may try this on Friday. My plan is to put her in with them on the Thursday night when it's dark and keep an eye on them when I let them into the run in the morning.

Then 8wk olds are lovely girls, they always run for cover if anything kicks off but they are so much bigger than her. Do think this will be the best option, it it gets too nast I can always bail her out.
