Don’t leave them in the dark. They are too young. They don’t have a hen to guide or protect them or keep them safe. They are too small and in her case especially cannot right themselves. They often don’t mean to hurt one another but...sometimes the pecking order stuff in even youn
I started one reply already and it disappeared so if it pops up ignore it. So here it goes again.
Don’t leave them in the dark. They are too young. They don’t have a hen to guide or protect them or keep them safe. They are too small and in her case especially cannot right themselves. They often don’t mean to hurt one another but...sometimes the pecking order stuff in even young chicks presents itself very early.
Always leave a light on and food and water down for them at all times 24:7 until at least three or four weeks. They cannot see in the dark. Chickens have night blindness basically. These chicks are very weak right now especially her if she is as you said and she cannot right her self if she is trampled and rolled over that hard over onto her back. My goodness. She could be hurt. I hope not. They are very hardy beings. More than we think so don’t give up easy on her. Separate her only for a few minutes to eat alone if you have to in order to insure she is getting enough food and water at good intervals during the day about every three hours and then let her eat with the others also. Just keep a good watch on their interactions with her to make sure they are not picking on her or abusing or pecking at her. Always leave enough light on for them at night and proper heat. A radiant heat source is best. If you see she is going down and not progressing further feel free to message me
@thepick4uchicks. I will be happy to help further. I had a smaller chick with my batch and we called her tinyTina and now she is a whopper and will probably be one of my first layers among my Cream Legbars this year. She is a beautiful hen. She was probably the most reserved for about six weeks and she has always been shy still with me but all the hens love her and have never picked on her because she was smaller and the largest leader of our flock loves her most so she always has a protector anyway among her best buddy. I bet she will come around. I never had to separate my girls but they were very sweet breeds. What breeds do you have in the five you bought? Just remember be like Motel 6 and always leave the light on! Lol. You can turn it off in a bout a month and go to a night light then go dark when they can roost a bit. This worked great with my flock and I have big big girls and they went outside at 11 weeks due to our extreme heat and we had a basement. They rooster the second night all on their own. I put them on their roost boards in their coop in late July the first night and the second night they went in all by themselves and roosted all by themselves. I never had to lock them up in their coop for 48 hours or anything like that for them to know it was their home. They knew it was right away and have never given me a problem. We would take them out their for a few hours in some late evenings to enjoy the grass in the run before the coop was completed while they were in our basement and they got familiar with things then and loved it. So I think that was the ticket to our success. Good luck with your baby and please keep us posted.
