Hello all, brand new to BYC. I have a lovely 9 month old french black copper maran rooster. He currently wears a no crow collar. He occssionally gets this foamy spittle coming out of his nostrils and mouth which then gets on his neck/waddle or comb when he shakes it off. He is in healthy condition otherwise. My question is this....is this a common side effect of wearing a no crow collar? He didnt have this issue before the collar. Looking for some answers as I find this alarming at times when it gets really foamy. Thank you in advance!
