They are 5 weeks old now. Today while giving them some melon flesh, I noticed mama didn't call them or let them eat it from her mouth. Instead she ran away from them and when they tried to eat it, she made this shrill noise. I thought she was getting to rough with them so I just took the flesh away from them. I took her out but she was making the weird clucking noises and the chicks were crying for her. So she doesn't like to share food with them. Is it just a start? What other signs are there when I should seperate her?
