One of my chicks is acting really strange. All the others go around with the broody mum like normal, but this one chick keeps running away from them all and hiding under the coop alone. If I take it out and put it back with the hen and other chicks it will stay with them a few minutes - then suddenly run off cheeping and go back under the coop. It is not getting picked on by the mother hen, or other chicks and it only started doing this today. It is 4 days old now. Yesterday I noticed it was trying to join in another older group of chicks and their mum, but it could not keep up with them, so went off on its own. At the moment the weather here is very hot, so I don't have to worry about it chilling. It seem quite happy on its own under the coop and is scratching about and eating fine. I never had a chick do this before.
