hi! I had to become a member... to finally get the byc expert opinion on whether my 5 week old chick (turn 6 weeks on Tuesday) is a rooster!! I don't know much about chickens, but I am beginning to get paranoid that one of my 'girls' is actually a 'boy'.... I don't think a rooster would go down well in my neighbourhood (city dweller) so if it is a rooster I should probably look to replace it sooner rather than later. The chicks were purchased as ISA browns at 4 weeks old.. they are supposably both female. All pictures show the chicks today at age 5wks + 4days. In The first picture the one I am suspect on is the chick on the LEFT hand side. I am quite confident the one on the RIGHT is a hen. The second picture shows a better shot of the tail on the bird I think is a rooster! In the first picture it didn't really look as it does in real life. In this shot the chick I think is a rooster is still on the LEFT hand side. This next pic shows a close up of the hen.. and also the tail and of the bird I am suspect on. It is worth noting that when Ipicked the chicks up (2 weeks ago) the bird I 'think' is a rooster had been pecked along it's back and had minimal feather between the wings or on top of the tail and on patches on it's side (well I think? it had been pecked!!!). The feathers began growing immediately once I had the birds home..... this final shot is of the 'suspects' head.... I can't wait to get someone else's opinion!
