how old can chicks be before you remove them from mum only reason why i am asking is i think my pekin maran wants back with the others but the chicks are only coming on 6 weks old roughly , i am not really around in the day to see what they are like but at night shes really really unsettled and constantly watches the other birds going to bed and acts like she wants to be with them . i know thier house has had red mite and its checked twice daily and treated 2 / 3 times a week so i dont know if its that thats bothering her as well but if i try and put her near another house i have in their section of the run she goes mad .
