This study aimed to investigate the impacts of egg removal or replacement with dummy eggs on behaviour, performance, and prolactin levels in Egyptian Baladi pigeons. Twenty pairs of mature Egyptian Baladi pigeons (12-18 months) were distributed into four groups (5 replicates each, one pair per replicate). Group 1 (G1): parents incubated two eggs without remove (control), G2: incubated eggs were removed and replaced by dummy faked eggs, G3: included the removal of 1st egg only after laying, and G4: each pair had two eggs removal after 2nd egg lay (incubate no eggs). Using a digital camera for recording and analysing the behaviour.
