I have a "flock" of 6 RIR and one of them has matured completely in less than 5 months. Full comb, etc. I believe it is crowing & saw it go after one of the others. The rest are just now starting to develop their combs, etc and I am thinking this must be a roo but see so many postings about girls acting like boys, cannot be sure. Wondering if the males mature faster. Also, he/she seems to have the squirts all the time! I tried cutting off all treats & it did not change, I tried the wormer and it did not change. I just saw a post that said to put Dawn in the water for worms so will try that & see if he/she gets better. Anyone know why one of the 6 with the same food, water & treats has the squirts and the rest don't? I need to get rid of this bird but am hesitant to give it to anyone if it is sick and it is not ACTING sick at all. Is pushy, mouthy and arrogant! Gets awful hard to clean up after him/her!! Thanks for all of the good info. Tho hard to find sometimes, most of my questions are answered without posting & I appreciate that more than I can say as a newbee!
